Racemic N-sulfonyloxaziridines as highly diastereoselective enolate hydroxylating agents: Enantioselective synthesis of (2S,3S)-3-amino-N- cyclopropyl-2-hydroxyhexanamide
A new, highly enantioselective synthesis of (2S,3S)-3-amino-N-cyclopropyl- 2-hydroxyhexanamide, a synthetic fragment of the experimental hepatitis C drug Telaprevir, has been described. Conjugate addition of the enantiomerically pure Davies lithium amide

Asymmetric aza-friedel-crafts reaction of 2-naphthol with tosylimines catalyzed by a dinuclear zinc complex
The first asymmetric aza-Friedel-Crafts reaction of 2-naphthol with tosylimines was developed via a dinuclear zinc catalyst (up to 98% ee). It provided a new method for the asymmetric synthesis of Betti base derivatives.
A general method for the preparation of N-sulfonyl aldimines and ketimines
(Chemical Equation Presented) A simple procedure to obtain N-sulfonyl imines involving the condensation of carbonyl compounds with p-tolyl or tert-butyl sulfinamides followed by oxidation with m-CPBA of the resulting N-sulfinylimines is reported. The meth
