Asymmetric Heck reaction-carbanion capture process. Catalytic asymmetric total synthesis of (-)-Δ(9(12))-capnellene

An asymmetric Heck reaction-carbanion capture process was realized for the first time, making possible the catalytic asymmetric synthesis of various functionalized bicyclo[3.3.0]octane derivatives 6 in up to 94% ee. Sodium bromide had interesting effects
