Synthesis of pyrano[2,3-c]carbazoles, pyrano[3,2-b]carbazoles and furo[3,2-b]carbazole derivatives via iodocyclization

Abstract

A simple and facile synthesis of pyranocarbazole derivatives starting from easily accessible O-propargylated carbazoles using iodocyclization in good yields is reported. A simple and facile synthesis of pyranocarbazole derivatives starting from easily accessible O-propargylated carbazoles using iodocyclization is reported.
