摘要

This report describes the gram scale synthesis of (S)-and (R)-2, 2, 4-trimethyl-4- (hydroxymethyl)-1, 3-dioxolanes using the Sharpless asymmetric dihydroxylation (AD) of the Weinreb amide of 2-methyl-2-propenoic acid. The 2-methylglycerol acetonides resultant from protection of the AD products were used as starting materials in the synthesis of O- benzyl ethers of the valuable C4-chiral building blocks (S)-and (R)-2-methylglycidol.
