Cis lithium enethiolates, generated from substituted dithioesters, undergo 1,4-addition with various β-monosubstituted α-unsaturated ketones.With acyclic enones one of the two resulting diastereomeric 5-oxodithioesters is predominantly formed (ratio up to 95 : 5).Its anti configuration was proven by chemical correlation in one case.Evidence for the stereospecificity of this Michael addition is given.
