Abstract
Optically active β-(trimethylsilyl)ethyl sulfoxides supported on Merrifield resin were treated with LDA and subsequently with methyl cinnamate at −78°C. Thermal treatment or reaction with TBAF liberated the optically active methyl 3-phenyl-5-trimethylsilylpent-4-enoate or methyl 3-phenylpent-4-enoate, respectively, in good yields with high enantioselectivity.
