Preparation rifamycin S derivatives (by machine translation)
The invention relates to a process for preparing rifamycin S derivatives. In accordance with the certain charging mode, as shown in formula II 3 – amino -4 – imino rifamycin S shown in formula III 4 – piperidone derivative in an organic solvent, in the presence of acetic acid to plated zinc powder, a condensation reaction, shown as formula I obtained of the rifamycin S derivatives; the feed way: the 3 – amino -4 – imino rifamycin S in the last step are added to a reaction system, the method avoids the 3 – amino -4 – imino rifamycin S is reduced and is hydrolysis of the, improving utilization ratio, mild reaction conditions, the relative shortening the reaction time, it can be efficient, high yield to obtain the rifamycin S derivatives, yield 80% or more, the content of 95% or more, overcomes the problems in the prior art long reaction time, the yield is low, a plurality of impurities, and the cost is high, and the operation is simple, high efficiency and environmental protection, is conducive to large-scale production.
