Abstract

An efficient and facile one-pot, three-component protocol for the synthesis of pyrimido[4,5-b]quinoline-4-amines from the condensation of 2-aminoquinoline-3-carbonitrile, N,N-dimethylformamide dimethyl acetal and primary amines under microwave irradiation is reported. This efficient, straightforward procedure led to the desired products in high yields without the need for a catalyst or for a tandem addition–elimination–cyclisation reaction.
