Nitroimidazoles XIII. Synthesis of Substituted (1-Methyl-5-Nitro-2-Imidazolyl) Isoxazoles [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering, 1998
The beta0diketone derivatives of nitroimidazole were synthesized from the reaction of magnesium salt of beta-ketoaccids 3 with imidazolide 4. The raction of beta-diketones with hydroxylamine hydrochloride afforded either the isoxazoles or the 5-hydroxyl ...

MICROBIAL OXIDATION OF AMINOIMIDAZOLES TO NITROIMIDAZOLES

open access: yesThe Journal of Antibiotics, 1968
The structural requirements for the microbial transformation of 2-aminoimidazoles to 2-nitroimidazoles by Streptomyces strain LE/3342 have been investigated. Substrates carrying an alkyl group in position 4 (or 5) were oxidized, the efficiency decreasing with the increase of the length of the chain.
