Abstract

An efficient method for the regioselective synthesis of uracil-, coumarin- and quinolone-fused benzosultams and benzosultones is reported. The method offers a synthetic route to highly functionalized sultam and sultone derivatives in 75–95% yield under mild conditions. Density functional theory studies have been used to explain the regio­selectivity in the synthesis of the coumarin- and quinolone-fused sultams and sultones.
