Abstract

A series of chiral α,β-unsaturated tert-butyl sulfoxides derivatives was synthesized by the Horner-Wadsworth-Emmons reaction in good (E)/(Z) ratios. The enantioselectivity up to 89% and the yield up to 90% were achieved. These sulfoxides could be important intermediates in asymmetric synthesis.
