摘要：

This review highlights the methods used for the synthesis of enaminonitriles of pyrano[2,3-c]pyrazole compounds. Their reactivity and synthetic importance were investigated. In this context, recent progress in the synthesis and use of enaminonitriles of pyrano[2,3-c]pyrazole as precursors for heterocyclic compounds is reviewed. The synthetic routes for preparation of enaminonitriles are based on multicomponent reactions including three- or four-component reactions. Enaminonitriles can be used as building blocks for carbocyclic five-, six-, and seven-membered heterocycles as well as fused heterocyclic compounds. The bibliography includes 94 references.
