and a propargylic organomagnesium reagent giving access to novel and densely functionalized 4‐allenyl‐2‐cyclohexenones (see scheme). These useful synthetic intermediates have been prepared through a cyclization process that involves newly reported reaction steps and an unusually high level of asymmetric induction.
