Abstract
A single element of chirality determines the configuration of the three newly formed stereogenic centers in the title reaction [Eq. (a)]. In particular, large (R = SiMe2Ph,tBu) and polar (R = OMe) substituents induce good diastereoselectivities. Simple ring‐opening reactions facilitate a stereoselective approach to acyclic products. (Figure Presented.)
