Facile synthesis of 4-substituted 3,4-dihydro-1H-2,1,3-benzothiadiazine 2,2-dioxides

A new method for the preparation of 4-substituted 3,4-dihydro-1H-2,1,3- benzothiadiazine 2,2-dioxides is described. Treatment of t-butyl N-phenylsulfamoylcarbamate derivatives (1) with different aldehydes afforded the corresponding intramolecular cyclized

Enantioselective synthesis of cyclic sulfamidates via Pd-catalyzed hydrogenation

Using Pd(CF3;CO2)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).
