摘要：

A two-step procedure for the synthesis of (2R,3S,4E)-5-benzenesulfonyl-2,3-isopropylidene-dioxypent-4-en- 1-yl-tosylate is described. The method involves the addition of lithio(phenylsulfonyl)methane to 2,3-O-iso-propylidene-D-erythronolactol and treatment of the resulting diols with tosyl chloride.
