  A carbohydrate approach to 4-hydroxy-2-cyclopentenone moiety of antitumor prostanoid Punaglandin IV via alkylation of ester uronate

  摘要：

  An efficient and stereoselective synthesis of a chiral precursor of 2-chloro-4-hydroxy-4-alkyl-2-cyclopentenone has been realized by alkylation of a sugar methyl uronate derived from 1,2-O-isopropylidene alpha-D-glucose with an acetonyl equivalent, and subsequent intramolecular Wittig reaction.
