  A highly stereoselective synthetic method for cis-2- hydroxymethyl-6-alkyltetrahydropyrans

  摘要：

  A highly stereoselective synthetic method for cis-2-hydroxymethyl 6-alkyltetrahydropyrans is described by an intramolecular 1,4-addition of alcohol to alpha,beta-unsaturated sulfoxide as a key reaction. This method is applied to syntheses of (+) and (-)-(cis-6-methyltetrahydropyran-2-yl)acetic acid.
