  Novel ring transformation of mesoionic oxazoles into 2(1H)-pyrazinones by the reaction with TosMIC

  摘要：

  Treatment of mesoionic 1,3-oxazolium-5-olates with TosMIC in the presence of a base causes a novel ring transformation affording 2(1H)-pyrazinones in moderate yields. The origin of C-2 carbonyl oxygen in the product was elucidated to be molecular oxygen, based on O-18-labeling experiments.[GRAPHICS].(C) 2013 The Authors. Published by Elsevier Ltd.

  In this report, we describe a new method for the synthesis of densely functionalized 2(1H)-pyrazinones. Treatment of mesoionic 1,3-oxazolium-5-olates with carbanions derived from activated methylene isocyanides (p-toluenesulfonylmethyl isocyanide (TosMIC) and ethyl isocyanoacetate) causes a novel ring transformation affording 2(1H)-pyrazinones in moderate to high yields. The cytotoxicity and antibacterial

  在这份报告中，我们描述了一种新的合成功能密集的2（1H）-吡嗪酮的方法。用衍生自活化亚甲基异氰酸酯（对甲苯磺酰基甲基异氰酸酯（TosMIC）和异氰基乙酸乙酯）的碳负离子处理中离子1,3-恶唑鎓5-酸酯，会引起新的环转化，从而以中等至高收率提供2（1H）-吡嗪酮。研究了一些所得产物的细胞毒性和抗菌活性，并且某些产物表现出肿瘤特异性的细胞毒性。
