Abstract

Procedure for obtaining 4- and 5-nitroimidazoles of formula I **(See formula)** wherein one of the radicals R1 and R2 signifies hydrogen or lower alkyl and the other is a nitro group, R3 signifies hydrogen or lower alkyl, optionally substituted, R4 signifies oxo or thioxo, R5 signifies heteroaryl and R6 and R7 are independent of yes, hydrogen or lower alkyl, or together, means the remaining part of a condensed benzene nucleus, if substituted, and of its salts, characterized in that a compound of formula II **(See formula)** it is condensed with a compound of formula III, or a tautomeric compound of formula IIIa **(See formula)** where R1, R2, R3, R4, R5, R6 and R7 have the indicated meanings, R'4 means an oxygen atom or, first of all, a sulfur atom and X and Y represent dissociable residues leaving a direct bond, or a compound of formula IV **(See formula)** where R3, R4, R5, R6 and R7 have the indicated meanings and at least one of the residues R'1 and R'2 means hydrogen and the other can also be lower alkyl, nitrate, or a compound of formula V **(See formula)** where R1, R2, R3, R5, R6 and R7 have the indicated meanings and R'4 represents an oxygen or sulfur atom, isomerizes, or in a compound of formula VI **(See formula)** where R1, R2, R3, R6 and R7 have the indicated meanings and R is lower alkyl, the -SR group is hydrolyzed to the oxo group and, if desired, in the compounds obtained, within the range of the definition of the final products, the substituents are introduced, modified or dissociated, and/or the racemate mixture, if obtained, is cleaved in the pure racemates and/or the racemates, if obtained, are separated into the optical antipodes and/or the salts, if appropriate obtained are transformed into the free bases or the free bases obtained are transformed into their salts.
