  Highly α-Selective Hydrolysis of α,β-Epoxyalcohols using Tetrabutylammonium Fluoride

  摘要：

  We report a simple method for the highly regio- and stereoselective hydrolysis of alpha,beta-epoxyalcohols. Treatment of enantiopure epoxyalcohols derived from Sharpless epoxidation with TBAF/H(2)O resulted in exclusive ring opening at the normally disfavored alpha-position, providing access to arabino- or lyxo-configured triols with full preservation of stereochemical purity. The method was applied in syntheses of 5-deoxy-L-arabinose (26) and a family of bicyclic acetals based on the insect pheromone hydroxybrevicomin (4).
