Arylmethyl and allylic cyclic sulfamides such as pyrroloisothiadiazinediones and pyridoisothiadiazinedione I [R = H, H2C:CHCH2; R1 = Ph, 4-t-BuC6H4, 4-MeOC6H4, 4-PhCOC6H4, 2-MeC6H4, 1-cyclohexenyl, Me(CH2)7CH:CH; X = CH2, CH2CH2; PMP = 4-MeOC6H4] were prepared in 43-89% yields and in 5:1-13:1 diastereoselectivities by intramol. alkene carboamination reactions of allyl-substituted heteroaryl sulfamides such as II (R = H, H2C:CHCH2; X = CH2, CH2CH2) with aryl triflates R1OTf [R1 = Ph, 4-t-BuC6H4, 4-MeOC6H4, 4-PhCOC6H4, 2-MeC6H4, 1-cyclohexenyl, Me(CH2)7CH:CH] in the presence of Pd(OAc)2 and the phosphine ligand CPhos III (Cy = cyclohexyl) in tert-butanol. The ligands of and conditions for palladium-catalyzed carboamination reactions may be tuned to favor either anti- and syn-aminopalladation reactions and thus to obtain different product diastereomers.
