Acetylenic chemistry, part 20: Ring opening of 3-azaisatoic anhydride with acetylenic amines: Synthesis of pyrido[2,3-d]pyrimidinones
摘要:
Ring opening of 3-azaisatoic anhydride with acetylenic amine gave the nicotinamides 3a-c. The reaction of triphosgene with the nicotinamides 3a-c yielded the pyrido[2,3-d]pyrimidinones 4a, 5b, 5c, and 7b.
