Benzofuran Synthesis through Iodocyclization Reactions: Recent Advances

Abstract

Recent advancements (2014-17) in the benzofuran synthesis through iodocyclization have been summarized. The successful use of various iodinating agents, bases, additives etc. make iodocyclization a versatile and efficient methodology. The methodology has been applied for the synthesis of more complex benzofuran derivatives, and may open interesting avenues in the area of heterocyclic chemistry.
