摘要

Stereoselective Michael addition and Michael-aldol tandem reaction of diorganyl diselenides and disulfides with conjugated alkynones mediated by samarium diiodide were studied. The reaction temperature was critical for the stereoselectivity. β-Organylselenoalkenones or β-organylthioalkenones and γ-organylselenoallylic alcohols orγ-organylthioallylic alcohols were prepared in good yields.
