  1,3-Dipolar cycloaddition reaction has proved to be most power protocol for various kinds of five-memberedheterocyclic compounds.Thus,1,3-dipolar cycloaddition of cyclic azomethine imines to acetylenic and olefinicdipolarophiles was the common method for the preparation of pyrazolo[1,2-a]pyrazolone derivatives.On our continualaim to providing concise construction protocol for spiroheterocyclic system,1 we investigated the 1,3-dipolarcycloaddition of cyclic azomethine imines and with some cyclic dipolarophiles.
