A novel and efficientthree-step protocol for synthesizing functionalizeddibenzothiophenes (DBTs) from common starting materials and by using palladium-catalyzed carbon-carbon and carbon-sulfur bondformations is presented. The reaction conditions offer significantly improved functional-group tolerance and regioselectivity as compared to previously reported methods.
