title: Studies towards the synthesis of the marine alkaloid chartelline C.
abstract: The 2,6-dibromoindole 5 underwent regioselective Sonogashira coupling at the 2 position with simple acetylenic partners. While, the imidazole-acetylene 16 failed to couple to 5, the cyclic carbonate 19 succeeded to give 20, which was further elaborated into the indole-imidazole 23.
