Influence of catalyst structure and reaction conditions on anti- versus syn-aminopalladation pathways in Pd-catalyzed alkene carboamination reactions of N-allylsulfamides.

The Pd-catalyzed coupling of N-allylsulfamides with aryl and alkenyl triflates to afford cyclic sulfamide products is described. In contrast to other known Pd-catalyzed alkene carboamination reactions, these transformations may be selectively induced to occur by way of either anti- or syn-aminopalladation mechanistic pathways by modifying the catalyst structure and reaction conditions.
