  Facile One-Step Synthesis of β-Alkoxy Lactone via Sequential Lactonization and 1,4-Addition of Alkoxide Group:  Total Synthesis of All Stereoisomers of Dihydrokawain-5-ol

  摘要：

  We describe here a divergent total synthesis of all of the four stereoisomers of dihydrokawain-5-ol starting from alpha-D-glucose. The approach involves the use of Ando's modification of Horner-Wadsworth-Emmons homologation to give a alpha,beta-unsaturated ester. Subsequently, lactonization and 1,4-addition of OMe group in one step provided a delta-lactone, which was converted into the target compounds in two steps.
