Abstract

An efficient, simple, and catalyst-free synthesis of spiroindeno1,2-bpyrido2,3-dpyrimidine-5,3`-indolines and spiroacenaphthylene-1,4`-indeno-1,5`-pyrido2,3-dpyrimidines by the three-component reaction of 1,3-indandione, amino uracils and isatins or acenaphthylene-1,2-dione in refluxing ethanol is reported.
