Recent progress on the synthesis of dibenzosultams through the intramolecular cyclization
Dibenzosultams,which have important biological activities,exhibit a wide range of application prospects in the field of medicinal chemistry.Therefore,it is of great significance to develop simple and efficient methods for constructing dibenzosultam skeletons.Among preparative methods for dibenzosultams,the intramolecular cyclization is the most efficient approach from a practical viewpoint,as it requires only simple experimental manipulations.In this review,the synthetic methods of dibenzosultams through the intramolecular cyclization reported in recent years were classified and summarized,in order to provide a reference for the design and syntheses of dibenzosultams.
