摘要：

Radical-mediated cyclization of norephedrine derived alpha-iodoamides 1 was found to be highly stereoselective (> 97.3) favouring diastereoisomer 2. Bicyclic lactams 2 were transformed in high yields into enantiomerically pure pyrrolidines 10. Transition state modelling with a force field developed ad hoc nicely predicts the stereochemical results.
