A diastereoselective rhodium-catalyzed arylation of N-(tert-butanesulfinyl)imines with sodium tetraarylborates is described. This method is general for constructing various chiral α-branchedamines and 2-substituted pyrrolidines with high diastereoselectivity. A practical asymmetric approach to access chiral amines has been developed involving the use of air-stable Rh catalysts and reagents and in

The enantioselective reductive cyclization of gamma-chloro N-(tert-butanesulfinyl)ketimines towards the short and efficient synthesis of (S)- and (R)-2-arylpyrrolidines (ee >99%) is described for the first time by treatment with LiBEt(3)H and subsequent acid deprotection.
