In a recent report, Nielsen and Skrydstrup (J. Amer. Chem. Soc. 2008, 130, 13145.) demonstrated that addition of a silyllithium reagent to the Ellman sulfinimine (1, R = t-Bu) yields the α-amino silane 3 with excellent diastereoselectivity. This efficient approach to these structures has been studied with both Ellman and Davis (R = p-MePh) sulfinimines in the context of silanediol protease inhibitor synthesis.
