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

Addition of organotrimethylsilane reagents to chiral N‐tert‐butanesulfinyl imines can be achieved in good yields and with excellent diastereoselectivities by employing TMSO−/Bu4N+ as a Lewis base activator in THF. A variety of aliphatic, aromatic, heteroaromatic and organometallic chiral imines were utilised as electrophiles for the synthesis of enantioenriched N‐tert‐butanesulfinyl amides. Remarkably

A diastereoselective nucleophilicmonofluoromethylation of tert-butanesulfinyl aldimines with α-fluoro-α-phenylthio-α-phenylsulfonylmethane (FTSM) as the reagent has been developed, which affords α-monofluoromethyl amines in good to excellent yields with excellent stereocontrol on both the monofluoromethylated carbon and the neighboring sulfonyl-bearing fluorinated carbon. The racemic α-fluoro-α-p
