Abstract

The selenolates are good nucleophiles for Michael addition reaction 8 and several selenolate anion-triggered Michael/aldol tandem reactions have been intensively studied. 9 Recently, our group has reported the stereoselective Michael/aldol tandem reaction of phenylselenomagnesium bromide with acetylenic sulfones and aldehydes to afford (Z)-β-phenylseleno-α-(p-tolylsulfonyl )allylic alcohols. 10 On the other hand, the Horner–Wadsworth–Emmons (HWE) reaction ...
