A variety of substituted 3-acyltetrahydrothiophenes can be prepared with high stereoselectivity in 50−70% yield by acid-promoted condensation of mercapto allylic alcohols 1 (X = S) with aldehydes and ketones. The mercapto allylic alcohol must be substituted at the internal alkene carbon and the terminal alkene carbon must be unsubstituted. This newsynthesis of tetrahydrothiophenes will be most useful
