Double Michael addition of dithiols such as 1,3-propanedithiol and 1,2-ethanedithiol to α,β-acetylenic carbonyl compounds in the presence of molecular sieve and dimethyl sulfoxide proceeds very smoothly to afford the corresponding β-keto 1,3-dithianes and

An efficient method has been found for the preparation of cyclic monodithioacetals of 1,3-dicarbonyl compounds using boron trifluoride etherate as the acid catalyst.Asymmetric 1,3-diketones react regioselectively in most of the cases tried.A study of the
