Abstract: | A new synthetic approach for pyrido2,3-d]pyrimidine 3-oxides and other pyrido2,3-d]pyrimidines has been developed. This bicyclic system readily undergoes ring opening to give a variety of products, depending on the reagent and reaction conditions.
Synthesen und Umwandlungen einiger Pyrido2,3-d]pyrimidine Zusammenfassung Synthesen von Pyrido2,3-d]pyrimidin-3-oxiden und einigen anderen Pyrido2,3-d]pyrimidinen werden beschrieben. Das bicyclische System reagiert leicht unter Ringöffnung, wobei entsprechend den Reaktionsbedingungen und Reagenzien verschiedene Produkte entstehen. |
