Mitt.: Ringöffnung von 3-Azaisatosäureanhydrid mit Acetylenaminen: Synthese von Pyrido[2,3-d]pyrimidinonen Summary: Ring opening of 3-azaisatoic anhydride with acetylenic amine gave the nicotinamides3 a-c. The reaction of triphosgene with the nicotinamides3 a-c yielded the pyrido[2,3-d]pyrimidinones4a,5b,5c, and7b.
