Gold-Catalyzed [5+2]- and [5+1]-Annulations between Ynamides and 1,2-Benzisoxazoles with Ligand-Controlled Chemoselectivity
This work describes two distinct annulations between ynamides and 1,2-benzisoxazoles with chemo-selectivity controlled by ligands. With IPrAuCl/AgNTf2, aryl-substituted ynamides undergo [5+2]-annulation reactions, whereas P(t-Bu)(2)(o-biphenyl)AuCl/AgNTf2 alters the chemoselectivity of the same ynamides to implement [5+1]-annulation reactions. C-13-Labeling experiments confirm that a 1,2-sulfonamide shift is involved in the [5+1]-annulation process. A plausible mechanism is postulated to rationalize the mechanisms of the two annulations.
