Abstract
Rifamycins are important antibiotics. This article describes the studies on rifamycins; i) the formation of dihydropyrimidorifamycins in the reaction of rifamycin S with hexahydro-1, 3, 5-triazines, ii) the formation of dihydropyrimidorifamycins from 3-formylrifamycin S and 3-formylrifamycin SV, iii) the reduction of the iminium bond of dihydropyrimidorifamycins, and iv) the reaction of 3-formylrifamycin S with Schiff bases and aminomethylethers.
