Abstract
Procedure for preparing rifamycins SV, of general formula: **(See formula)** wherein R1 and R2 are independently selected from: a) hydrogen, b) alkyl, c) alkenyl, d) alkynyl, e) aryl, f) aralkyl, g) heterocyclic, h) cycloalkyl, and in which formula only one of radicals R1 and R2 can be hydrogen or lower alkyl of 1 to 4 carbon atoms; and if hydrogen or lower alkyl is present, the other symbol for R1 or R2 should be substituted alkyl or hydroxyalkyl of at least 5 carbon atoms or a substituted alkyl other than the dimethylaminoethyl radical, or a member of groups c) to h) where aryl is other than phenyl and p-carboxyphenyl, and aralkyl is other than benzyl, and where R3 is -H or OH3CO; and derivatives 16, 17, 18, 19, 28, 29-hexahydro and 27-demethoxy-27-hydroxy; characterized by comprising contacting a 3-formyl-rifamycin of the formula: **(See formula)** where R3 is defined as above, or the corresponding hexahydro derivative, with a hydrazine of formula H2N-NR1R2 where R1 and R2 are defined as above.
