It's the addition of Lewis acids that does it! Reaction (a) proceeds with diastereoselectivities ≥ 100:1 if the radical transfer takes place in the presence of Lewis acids such as MgI 2 , MgBr 2 , or Sc(OTf) 3 . The influence of the substituents at position 4 of the oxazolidinone ring on the allylation was also studied.
