Abstract
A series of tetrahydropyran-4-one and tetrahydrothiopyran-4-one derivatives with 3-aryl or 3,6-diaryl substituents were prepared by double conjugate addition of water or H 2 S to divinyl ketones. These starting materials were accessed in two steps by conversion of lithiated α-bromostyrene derivatives with acrolein or cinnamaldehyde and subsequent oxidation of the divinylalcohols with MnO 2 .
