The reactions of 3-arylmethylene-2(3H)-furanones with N-nucleophiles proceeds with the opening of the lactone ring. Further course of the reaction depends on the structure of initial reagent, the capacity of the nucleophile and the reaction conditions and can lead to the formation of amides, 4-oxoalkanoic hydrazides, benzofurans, furopyridines, phenanthrenes, pyridazinones and other recyclization products. This opens a convenient way to obtain a large number of new compounds, both cyclic and acyclic, representing interest as reagents in organic synthesis and biologically active objects.
