N-Iodosuccinimide-promoted Regioselective Selenylation of 4H-Pyrido-[1,2-a]-pyrimidin-4-ones with Diselenides at Room Temperature

Lina Guo et al.

Summary: A novel and efficient method for regioselective selenylation of 4H-pyrido-[1,2-a]-pyrimidin-4-ones with diselenides at room temperature has been developed. The procedure is catalyzed by N-iodosuccinimide under metal-free conditions and provides good to excellent yields of C3 selenylation products across a broad range of substrates. Furthermore, sulfenylation with diphenyl disulfides and 4-methylbenzenethiol in this transformation is also successful.

NIS-promoted intramolecular cyclization of allenamides for the synthesis of tetrahydro-β-carbolines

Na Ding et al.

Summary: An NIS-promoted intramolecular cyclization of allenamides was developed for the synthesis of tetrahydro-8-carbolines. These reactions proceed rapidly and tolerate a broad scope of substrates. The obtained halides can undergo functional group diversification via palladium catalyzed coupling reactions, potentially serving as intermediates for the synthesis of valuable compounds.
