A series of 2,3-dihydrothiopyran-4-one derivatives with unequal substituents in the 2- and 6-position have been prepared by double conjugate addition of sulfide to enynones. These starting materials were accessed in two steps from terminal alkynes and alpha,beta-unsaturated aldehydes. (c) 2006 Elsevier Ltd. All rights reserved.

3-Oxo-1-pentene-4-ynes were converted with sodium sulfide or hydrogensulfide to give 2,6-disubstituted 2,3-dihydrothiopyran-4-one derivatives. The starting materials were prepared in two steps from terminal alkynes and alpha,beta-unsaturated aldehydes.
