Novel Method

An efficient N-heterocyclic carbene-assisted one-pot reaction synthesis of 2,3-dihydropyrimido[4,5-d] pyrimidin-4(1H)-ones from 2-(ethoxymethylene)malononitrile, guanidines (or amidines) and ketones (or aldehyde) has been developed. The novel method provides a highly efficient synthesis of pyrimido[4,5-d]pyrimidinering from materials with no heterocyclic structures.
