摘要

A reaction pairing strategy centered on utilization of a reaction triad (sulfonylation, SNAr addition and Mitsunobu alkylation) generating skeletally diverse, tricyclic and bicyclic benzofused sultams is reported. Pairing sulfonylation and SNAr reactions yields bridged, tricyclic and bicyclic benzofused sultams. Application of the Mitsunobu reaction in a sulfonylation-Mitsunobu-SNAr pairing allows access to benzthiazocine-1,1-dioxides, while a simple change in the order of pairing to sulfonylation-SNAr-Mitsunobu affords structurally different, bridged tricyclic benzofused sultams.
