A 4-dimethylaminopyridine (DMAP)-promoted high stereoselectivity method for the synthesis of polysubstituted spiropropane pyrazolone was developed. A series of target compounds were synthesized from using pyrazolone, aromatic aldehyde and bromoacetate as raw materials, and DMAP as a base with high yield via three-component one-pot reaction. This reaction has the advantages of simple operation, high yield and good diastereotopic selectivity. In addition, this synthetic method is of great value for the study of spiropropane.

Key words: one-pot synthesis, multicomponent reactions, spirocyclopropane, pyrazolones, 4-dimethylaminopyridine (DMAP)
