Application of a Rhodium-Catalyzed Addition/Cyclization Sequence toward the Synthesis of Polycyclic Heteroaromatics
摘要:
A cascade rhodium-catalyzed addition/cyclization reaction of bifunctional heteroromatic boronate esters to strained bicyclic alkenes has been developed. This method provides an efficient route to generate a variety of polycyclic heteroaromatic molecules containing benzothiophene, benzofuran, and indole moieties.
