Imidazole

Discovery


Imidazole was first synthesized by Heinrich Debus in 1858, but various imidazole derivatives had been discovered as early as the 1840s. His synthesis, as shown below, used glyoxal and formaldehyde in ammonia to form imidazole. This synthesis, while producing relatively low yields, is still used for creating C-substituted imidazoles.


In one microwave modification the reactants are benzil, formaldehyde and ammonia in glacial acetic acid forming 2,4,5-triphenylimidazole (Lophine).

Structure and properties

Imidazole is a 5-membered planar ring, which is soluble in water and other polar solvents. It exists in two equivalent tautomeric forms because the hydrogen atom can be located on either of the two nitrogen atoms. Imidazole is a highly polar compound, as evidenced by a calculated dipole of 3.61D, and is entirely soluble in water. The compound is classified as aromatic due to the presence of a sextet of -electrons, consisting of a pair of electrons from the protonated nitrogen atom and one from each of the remaining four atoms of the ring.


Some resonance structures of imidazole are shown below:


Amphotericity


Imidazole is amphoteric, i.e. it can function as both an acid and as a base. As an acid, the pKa of imidazole is 14.5, making it less acidic than carboxylic acids, phenols, and imides, but slightly more acidic than alcohols. The acidic proton is located on N-1. As a base, the pKa of the conjugate acid (cited above as pKBH+ to avoid confusion between the two) is approximately 7, making imidazole approximately sixty times more basic than pyridine. The basic site is N-3.


Preparation

Imidazole can be synthesized by numerous methods besides the Debus method. Many of these syntheses can also be applied to different substituted imidazoles and imidazole derivatives simply by varying the functional groups on the reactants. In literature, these methods are commonly categorized by which and how many bonds form to make the imidazole rings. For example, the Debus method forms the (1,2), (3,4), and (1,5) bonds in imidazole, using each reactant as a fragment of the ring, and thus this method would be a three-bond-forming synthesis. A small sampling of these methods is presented below.


Formation of one bond


The (1,5) or (3,4) bond can be formed by the reaction of an imidate and an -aminoaldehyde or -aminoacetal, resulting in the cyclization of an amidine to imidazole. The example below applies to imidazole when R=R1=Hydrogen.


Formation of Two Bonds


The (1,2) and (2,3) bonds can be formed by treating a 1,2-diaminoalkane, at high temperatures, with an alcohol, aldehyde, or carboxylic acid. A dehydrogenating catalyst, such as platinum on alumina, is required.


The (1,2) and (3,4) bonds can also be formed from N-substituted -aminoketones and formamide and heat. The product will be a 1,4-disubstituted imidazole, but here since R=R1=Hydrogen, imidazole itself is the product. The yield of this reaction is moderate, but it seems to be the most effective method of making the 1,4 substitution.


Formation of Four Bonds


This is a general method which is able to give good yields for substituted imidazoles. It is essentially an adaptation of the Debus method called the Debus-Radziszewski imidazole synthesis. The starting materials are substituted glyoxal, aldehyde, amine, and ammonia or an ammonium salt.


Formation from other Heterocycles


Imidazole can be synthesized by the photolysis of 1-vinyltetrazole. This reaction will only give substantial yields if the 1-vinyltetrazole is made efficiently from an organotin compound such as 2-tributylstannyltetrazole. The reaction, shown below, produces imidazole when R=R1=R2=Hydrogen.


Imidazole can also be formed in a vapor phase reaction. The reaction occurs with formamide, ethylenediamine, and hydrogen over platinum on alumina, and it must take place between 340 and 480 C. This forms a very pure imidazole product.


Biological significance and applications


Imidazole is incorporated into many important biological molecules. The most pervasive is the amino acid histidine, which has an imidazole side chain. Histidine is present in many proteins and enzymes and plays a vital part in the structure and binding functions of hemoglobin. Histidine can be decarboxylated to histamine, which is also a common biological compound. It is a component of the toxin that causes urticaria, which is another name for allergic hives. The relationship between histidine and histamine are shown below:


One of the applications of imidazole is in the purification of His-tagged proteins in immobilised metal affinity chromatography(IMAC). Imidazole is used to elute tagged proteins bound to Ni ions attached to the surface of beads in the chromatography column. An excess of imidazole is passed through the column, which displaces the His-tag from nickel co-ordination, freeing the His-tagged proteins.


Imidazole has become an important part of many pharmaceuticals. Synthetic imidazoles are present in many fungicides and antifungal, antiprotozoal, and antihypertensive medications. Imidazole is part of the theophylline molecule, found in tea leaves and coffee beans, which stimulates the central nervous system. It is present in the anticancer medication mercaptopurine, which combats leukemia by interfering with DNA activities.


Pharmaceutical derivatives


The substituted imidazole derivatives are valuable in treatment of many systemic fungal infections.


Ketoconazole


Miconazole


Fluconazole


Itraconazole


Voriconazole


Industrial applications


Imidazole has been used extensively as a corrosion inhibitor on certain transition metals, such as copper. Preventing copper corrosion is important, especially in aqueous systems, where the conductivity of the copper decreases due to corrosion.


Many compounds of industrial and technological importance contain imidazole derivatives. The thermostable polybenzimidazole PBI contains imidazole fused to a benzene ring and linked to a benzene, and acts as a fire retardant. Imidazole can also be found in various compounds which are used for photography and electronics.


Salts of imidazole


Salts of imidazole where the imidazole ring is in the cation are known as imidazolium salts (for example, imidazolium chloride). These salts are formed from the protonation or substitution at nitrogen of imidazole. These salts have been used as ionic liquids and precursors to stable carbenes. Salts where a deprotonated imidazole is an anion are also possible; these salts are known as imidazolide salts (for example, sodium imidazolide).


Related heterocycles

Dihydroimidazole or benzimidazoline, an analog where 4,5-double bond is saturated.


Pyrrole, an analog with only one nitrogen atom in position 1.

Cherub with Chariot Egg

Design


The exact design of the Cherub with Chariot Egg is unknown and there is no known drawing or photograph of the egg. There is a brief description from the imperial records in the Russian State Historical Archives in Moscow which describes the gift as "Angel pulling chariot with egg - 1500 roubles, angel with a clock in a gold egg 600 roubles." According to Marina Lopato in Faberg: Imperial Jeweller (1993) this description means the clock is inside the gold egg, which is in the chariot being pulled by the angel. Faberg's invoice carries a similar description, itemizing a cherub pulling a chariot with an egg and a cherub with clock in a gold egg. These two descriptions are backed up by the 1917 inventory of seized imperial treasure which reads "gold egg, decorated with brilliants (diamonds), a sapphire; with a silver, golded [sic] stand in the form of a two-wheeled wagon with a putto."

History of the egg


The egg would have been presented to Maria Feodorovna on April 24th, 1888 by Alexander III. The egg was kept in the Gatchina Palace in 1891, and was one of 40 or so eggs sent to the Armory Palace of the Kremlin in 1917 after the Revolution by the Provisional Government. In 1922 it was transferred to the Sovnarkom, after which the exact whereabouts of the egg are unknown. In the 1930's Victor and Armand Hammer may have purchased the egg. A sales catalog for Armand Hammer's 1934 exhibition at Lord and Taylor in New York describes a "miniature silver armour holding wheelbarrow with Easter Egg, made by Faberg, court jeweler" which seems to describe the Cherub with Chariot Egg. Armand Hammer may have been unaware of the significance of this item if it was in fact the 1888 Imperial egg, since he had a habit of promoting imperial items yet did not make an effort to promote this egg. Whether this was the 1888 egg, and where it is today is unknown.

What is jade?


    The dictionary says, it is a mineral, texture thin and shiny.


    But Jade is not just minerals, mineral voluminous, people do not cherish all the jade minerals like emotions. Jade and I was not specifically bond, had no intention of jade collection, there is no specifically to find out about jade, but the feeling of admiration for people jade mentality, they love and care for jade, jade all the emotional investment of all let me surprise, so that I am touched. This is not because of the priceless jade, the same expensive gold and silver and even diamonds, are not such a respected; not because of the beautiful luster of jade, the world's glorious beauty of the material found everywhere - everything is not as jade, as into the the depths of the human mind, and people form lasting bonds with people associating with the people are not even into a puzzled feeling.

    This is the jade. It is a common substance, but not a common substance.


    Many people close affinity with the jade, they can tell themselves, relatives and friends and jade beautiful legends and stories, from time to time I will because they are real feelings, echocardiography fascinating. From which I realized, in fact, I and jade there is also a margin, I do not jade, and my heart there is a jade, as long as I know the location of jade in people's minds, which in my mind, also left his position.


   


    I felt the magic jade, enormous charm.

Understanding and insights for the jade, I did not dip and the fur on the jade rich and profound, I am more at a loss for far-fetched, but the spiritual and vivid jade infected me, so I had to take note of these, "Yu Ren." In the future without talking about the dinner, party, trip, I still often hear talk of jade, often Guanyu presence.


    No one would have other physical substances such input will not be someone from the bank card from the wallet pulls out, will not put a gold necklace or a diamond ring in public as a talking appreciate the goal. Only jade, people constantly talking about, it was demonstrated, some adding "Yu Ren" team. I am afraid there is very little other collection, can be so homely, so universal, so wherever they appeared at the time where people's discourse.


   


    Jade in the people's livelihood, the show a kind of ordinariness, and strange is that only it, and since ancient times has been the most noble symbol. "Yujiebingqing," "Jade bone Bing Ji", "I'd rather Stick to your guns is not", can be described as ordinary people, is the highest praise yet.


    Jade is a substance, but also a spirit, which exists in ordinary reality, but also exists in the human spirit and soul, in reality, it can be for sale, carved Synthesizer, in the person's heart, it always priceless.
