Oxidation of nitrogen-containing heterocycles using biocatalysts

Article abstract of DOI:10.1007/BF02495611

A method for stereospecific hydroxylation of 1,2-dihydro-3H-1,4-benzodiazepin-2-ones using free and immobilized cells of actinomycetcs as biocatalysts was developed. The hydroxylation under the action of yeast results in the formation of racemates. Actinomyces do not hydroxylate quinazolinones, quinoxalinones, and tetrahydro-1,5-benzodiazepin-2-ones; derivatives of 1,2,3,4-tetrahydro-1,5-benzodiazocin-2-ones are transformed into 2-[N-(3-acetylaminopropionyl)amino]benzophenones.
