Abstract

Addition of amines to dibenzylidene sulfamide1 a yields the correspondingSchiff bases3 a, b and monobenzylidene sulfamide2. Reaction of several dibenzylidene sulfamides1 with various lithium-amides gives N1-substituted N2-benzylsulfamoyl-benzamidines7 a-k via an intramolecular hydride transfer reaction, whereas by treatment of1 a with sodium amide 2-benzyl-3,5-diphenyl-3,4-dihydro-2H-1,2,4,6-thiatriazine-1,1-dioxide8 is obtained, which on hydrolysis yields9 and11. Alkylation products are described, the isomeric products12a/13a and12b/13b are isolated, their structures are confirmed by synthesis, IR and NMR-spectra.
