The oxoketene dithioacetals (2a-k) derived from a variety of cyclic and acyclic active methylene ketones undergo 1,2-addition with methylmagnesium iodide to give the alcohol acetals (3a-k) which, on subsequent boron trifluoride-ether catalysed methanolysi
α-OXOKETENE DITHIOACETALS: VERSATILE SUBSTRATES FOR 1,3-CARBONYL TRANSPOSITIONS

A two step procedure for the conversion of α-oxoketene dithioacetals to β-substituted α,β-unsaturated thioesters or acids is described.The overall transformation represents a 1,3-carbonyl transposition in which the original ketone carbonyl emerges as the carbonyl of an acid or thioester.The resulting thioesters and acids constitute versatile acylating reagents in accord with established procedures.
