A general synthesis of quinolinones and benzothiazine 1,1-dioxides is presented. A series of N-phenylacrylamides and N-phenylethylenesulfonamides were studied for their ability to undergo ring closing methathesis to yield the corresponding quinolinones and benzothiazine 1,1-dioxides, respectively. The reactions are general in scope and represents a mild method for the preparation of these heterocycles
提出了喹啉酮和苯并噻嗪1,1-二氧化物的一般合成方法。研究了一系列的N-苯基丙烯酰胺和N-苯基亚乙基磺酰胺的能力,使其能够进行闭环分解,分别得到相应的喹啉酮和苯并噻嗪1,1-二氧化物。反应是一般性的,代表了制备这些杂环的温和方法。
