Enantio- and diastereoselective catalytic alkylation reactions with aziridines.

Enantio- and diastereoselective catalytic alkylation reactions with aziridines.

The first asymmetric phase transfer catalyzed alkylation reaction of a range of carbon acids with N-sulfonyl aziridines is reported. When 10 mol % of a cinchona derived quaternary ammonium salt was employed as the catalyst under mildly basic conditions, N-o-(trifluoromethane)benzenesulfonyl aziridin...
