Abstract

Using Pd (CF3CO2) 2/(S, S)-f-binaphane as the catalyst, an efficient enantioselective synthesis of cyclic sulfamidates was developed via asymmetric hydrogenation of the corresponding cyclic imines in 2, 2, 2-trifluoroethanol at room temperature with high enantioselectivities (up to 99% ee).
