Alternative syntheses of the C9-C15 and C1-C5 segments of erythronolide A via regio- and stereo-selective reductive ring opening of 2,3-epoxy alcohols.

The DMPM (3,4-dimethoxybenzyl) protection for hydroxy function was deprotected more readily than the MPM (p-methoxybenzyl) protection by DDQ oxidation under neutral conditions, and applied to the synthesis of some synthons to macrolide and polyether antibiotics.
