acetylenic derivatives to give specifically substituted pyridones or pyridines. The observed selectivity can be explained in terms of HO-LU interactions for the reagents and two competitive retro Diels-Alder reactions of the primary bicycloadducts. With cyanotosylate as dienophile no pyrimidone derivative but a new 2(1H)-pyrazinone is obtained.
各种取代的2(1H-吡嗪酮)与炔属衍生物反应生成特定取代的吡啶酮或吡啶。观察到的选择性可以通过试剂的HO-LU相互作用和一级双环加合物的两个竞争性Diels-Alder反应进行解释。作为双亲物,没有嘧啶酮衍生物,但是获得了新的2(1H)-吡嗪酮。
