DIASTEREOSELECTIVITY IN CYCLOPROPANATION AND EPOXIDATION REACTIONS OF CHIRAL (E)-CROTYLSILANES - ASYMMETRIC-SYNTHESIS OF SUBSTITUTED TETRAHYDROFURANS

[摘要] Functionalized (E)-crotylsilanes 1 bearing a bis-homoallylic hydroxyl group undergo diastereoselective cyclopropanation and epoxidation reactions to produce substituted tetrahydrofurans 3 and 5 respectively after an acid catalyzed heterocyclization.
