3-METHYL-γ-BUTYROLACTONE AS A SOURCE OF 2-METHYL-3-HYDROXYKETONES AND 2-METHYL-1,3-DIOLS: A SYNTHESIS OF THE C19-C27 FRAGMENT OF RIFAMYCIN S BY LINEAR ITERATION

3-Methyl-γ-butyrolactone has been employed as a source of 2-methyl-3-hydroxyketones after functioning as a template for the preparation of enantiomerically pure propionate chains.This method is exemplified by the preparation of the C19-C27 propionate frag
