3-Methyl-r-butyrolactone has been enployed as a source of Z-methyl-3-hydroxyketones after functioning as a tenplate for the preparation of enantiomerically pure propionate chains. This method is exemplified by the preparation of the C&,-C27 propionate fragment utilized by Kishi in his synthesis of r
