Abstract

Scheme 1)[2] and murrayazoline (1d, Scheme 1).[3] They have received significant attention as synthetic targets due to their intriguing structural features and promising biological activities. A large number of classical and nonclassical methods have been developed for the synthesis of carbazole and dibenzofuran frameworks.[4] Since transition-metal-catalyzed intermolecular formation of CÀN/CÀO bond through nitrogen/oxygen nucleophilic ...
