摘要

It was in 1963 that Huisgen laid out the classification of 1,3-dipoles and the concepts for 1,3-dipolar cycloaddition reactions,although it was not until 1976 that the first intramolecular 1,3-dipolar cycloaddition reaction of an azomethine ylide was reported.Since then,impressive developments have been described in this area,with the establishment of various useful methods for the formation of azomethine ylides and the determination of the requirements for a successful intramolecular cycloaddition reaction.Use of this methodology for the synthesis of pyrrolidine-and pyrrole-containing natural products has been expanding rapidly.This review aims to describe the background and mechanisms of azomethine ylide formation and intramolecular cycloaddition,giving a critical account including the
