One-Pot Oxapropellane Skeleton Formation Based on Conjugate Addition

Reactions of five- and/or six-membered-ring ketones 1-5 possessing an ω-halogenoalkyl group and α',β'-unsaturated ester function at the α-position with diorganocuprates afforded the oxapropellane compounds 20-24 in a one-pot, three-step procedure via 1,4-
