A Review of Dicyclization Reaction for the Construction of Five-and Seven-Membered Heterocyclic Skeleton
Five-and seven-membered heterocyclic derivatives represented by pyrrolizazide,furooxepin and oxepinopyrrole have important pharmacological activities.Exploring a new time-saving and green method for constructing five-and seven-membered heterocyclic skeleton has always been a research hot piont in chemical synthesis.This paper discusses the application of dicyclization reaction in the construction of five-and seven-membered heterocyclic skeleton,which provides valuable enlightenment for the efficient construction of heterocyclic skeleton.
