Aspergillic acid acetic acid gives a diketopiperazine. Hydrolysis with HBr yields a mixture of -leucine and -isoleucine. These reaction schemes can be seen below: Aspergillic acid Aspergillic acid is an organic chemical compound with the molecular formula CHNO. It has a pale yellow crystalline appearance. Aspergillic acid is most commonly known as an antibiotic and antifungal agent that is derived from certain strains of the fungus "Aspergillus flavus". In 1940 Edwin C. White and Justina H. Hill discovered that a fungal strain of "Aspergillus flavus" growing in a surface culture on a tryptone-salt was capable of producing a bactericidal filtrate. It has
Benzilic acid is regulated by the Chemical Weapons Convention. It is also monitored by law enforcement agencies of many countries, because of its use in the manufacture in hallucinogenic drugs. Benzilic acid Benzilic acid is an organic compound with formula or ()(HO)C(COOH). It is a white crystalline aromatic acid, soluble in many primary alcohols. Benzilic acid can be prepared by heating mixture of benzil, ethanol and potassium hydroxide. Another preparation, performed by Liebig in 1838, is the dimerization of benzaldehyde, to benzil, which is transformed to the product by the benzilic acid rearrangement reaction. Benzilic acid is used in the manufacture of
