Synthesis of tetrahydropyran-4-ones and thiopyran-4-ones from donor-substituted α-bromostyrene derivatives

Tetrahydropyran-4-one and tetrahydrothiopyran-4-one derivatives with a 3-aryl substituent were synthesized by double-conjugate addition of water or H2S to divinyl ketones. These starting materials were prepared in two steps by conversion of lit

Synthesis of 3-aryl-substituted tetrahydropyran-4-ones and tetrahydrothiopyran-4-ones

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 H2S to divinyl ketones. These starting materials were accessed in two step
