  The title compounds were obtained from reaction of variously substituted 2(1H)pyrazinones with acetylenic derivatives. Experimental evidence points out to a two step mechanism : a Diels Alder cycloaddition followed by immediate decomposition of the adducts into the title products via two competitive retro Diels Alder reactions. The product distribution, which is shown to be highly dependent on the

  标题化合物获自各种取代的2（1H）吡嗪酮与炔属衍生物的反应。实验证据指出了两步机理：Diels Alder环加成反应，然后通过两个竞争性Diels Alder逆向反应将加合物立即分解为标题产物。一个简单的FMO模型可以说明产物分布高度依赖于反应物的取代模式。

  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.

• One step synthesis of 1,5-diaryl pyridin-2(1H)-ones from 2-aryl vinamidinium salts and N-aryl cyanoacetamides

  A one step, direct method for the synthesis of 1,5-diaryl pyridin-2(1H)-one derivatives by condensation of 2-aryl vinamidinium salts with N-aryl cyanoacetamides has been developed. This method can conveniently provide the corresponding 1,5-diaryl pyridin-2(1H)-one derivatives with various substituents in good yields and overcome the drawbacks of existing methods such as poor substrate scope, heavy metal pollution, and low yields. The formation mechanism of the products was illustrated. (C) 2014 Elsevier Ltd. All rights reserved.
