The reaction of 6-aminopyrimidines 4 with 3-formylchromone under microwave irradiation in dry media and classical heating in absolute ethanol afforded in all cases the unexpected 6-hydroxy-6,9-dihydrobenzopyranopyrido[2,3-d]pyrimidin-8-ones 6a-e (alternatively named, 6-hydroxy-6,9-dihydro-5-oxa-9,11
