2-vinylbenzofurans and 3-vinylfuropyridines. Attempts to extend the cascade to [4.4.0] binuclear heterocycles met with limited success. An alternative, two-step entry to such ring systems has been developed using the palladium-induced cyclization/hydride capture methodology. A new route to isoquinilinones from simple benzamides is also disclosed.
本文描述了进一步的研究,以炔丙基缩醛与芳基锂的分子内碳甲酸酯化反应生成2-乙烯基苯并呋喃和3-乙烯基呋喃吡啶。尝试将级联扩展至[4.4.0]双核杂环的尝试取得了有限的成功。使用钯诱导的环化/氢化物捕获方法已经开发了进入这种环系统的另一种两步方法。还公开了从简单的苯甲酰胺制异喹啉酮的新途径。
