• -diamines [111] (Scheme 21A). The proposed reaction mechanism suggests the generation of a triarylamine radical cation, which oxidizes the vinylarene by a SET mechanism. The resultant vinylarene cation radical X is attacked by the sulfamide nucleophile with Y formation. The second oxidative SET leads to the

While the latter showed very low affinity for the protein, the former displayed Ki values between 88 nM
