Synthesis of new pyrido[2,3-d]pyrimidin-5-one, pyrido[2,3-d]pyrimidin-7-one, and pyrimidino[4,5-d][1,3]oxazine derivatives from 5-acetyl-4-aminopyrimidines

Methods were developed for the synthesis of new pyrido[2,3- d ]pyrimidine and pyrimidino[4,5- d ][1,3]oxazine derivatives. When heated under reflux with MeONa in BuOH, 5-acetyl-4-aminopyrimidines, acylated with carboxylic anhydrides or acid chlorides, are transformed into pyrido[2,3- d ]pyrimidin-5-...
