  Highly Stereoselective Epoxidation of α-Methyl-γ-hydroxy-α,β-unsaturated Esters:  Rationalization and Synthetic Applications

  摘要：

  The diastereoselectivity of the nucleophilic epoxidation of gamma-hydroxy-alpha, beta-unsaturated esters having a methyl substituent at the alpha- or beta-position was investigated. Epoxidation of the alpha-methyl-substituted enoate was highly stereoselective, giving rise to the syn isomer. This finding was used to perform an enantioselective synthesis of a natural product having a beta-hydroxy-alpha-methylene-gamma-butyrolactone motif. The nucleophilic epoxidation of enoates was found to be irreversible. Models to explain the observed stereoselectivities are proposed.
