A SIMPLE SYNTHESIS OF α,β-UNSATURATED CARBONYL COMPOUNDS BY TRAPPING THE MICHAEL ADDITION-ENOLATE ANION WITH METHANESULFINYL CHLORIDE

Fujisawa, Tamotsu,Noda, Atsunari,Kawara, Tatsuo,Sato, Toshio

, p. 1159 - 1160 (1981)

Trapping of an enolate anion, formed by the Michael addition, with methanesulfinyl chloride and subsequent desulfinylation is found to be a useful method for the synthesis of various α,β-unsaturated carbonyl compounds.Synthetic utility of this method is demonstrated in the synthesis of geraniol, nerol, farnesol, and dihydrojasmone.
