The suitability of chiral oxazolidinones in the SmI2-mediated C–C bond generation between the imide functionality of an N-acyloxazolidinone unit and an olefinic radical acceptor, in both inter- and intramolecular reactions, was investigated. It was shown that the products from an Evans asymmetric alkylation can undergo direct carbon–carbon bond formation with an acrylamide providing chiral acyclic
