Enantioselective Pd-catalyzed hydrogenation of enesulfonamides

Asymmetric hydrogenation of cyclic enesulfonamides affords chiral cyclic sulfonamides using Pd(OCOCF3)2/diphosphine complexes as catalysts with up to 98% ee.

Novel method for the synthesis of 3-monosubstituted six-membered benzosultams

3-Monosubstituted six-membered benzosultams with a wide range of functional groups were prepared by simple and convenient two-step procedures. o-Lithiation of N-Boc-o-toluenesulfonamide followed by reaction with aldehydes gave carbinol sulfonamides, which were converted to 3-monosubstituted six-membered benzosultams via TMSCI/NaI/MeCN reagent mediated cyclization. The mechanism and the scope of this novel transformation are studied.
