of organometallic reagents (Grignard and dialkylzinc) to new vinyl diepoxides was examined. Cyclic vinyl diepoxides undergo clean SN2′ reactions to afford oxa-bridged systems of various sizes after a domino intramolecular O-alkylation reaction. Acyclic vinyl diepoxides are alkylated in good yields and with good regioselectivities, and a new catalyticenantioselectivedesymmetrization reaction to afford
