Ruthenium(II)-catalyzed reactions of cyclic diazodicarbonyl compounds with β-ketoamides for chemo- and stereoselective construction of cyclohexanone-fused γ-butenolides are described. This study represents the first example of the addition of an enol substrate which is formed by the tautomerization of the β-ketoamides to the electrophilic carbene center for unusual cyclization through amide cleavage
描述了钌(II)催化的环状重氮二羰基化合物与β-酮酰胺的化学和立体选择性构建,环己酮稠合的γ-丁烯内酯。这项研究代表了添加一个烯醇底物的第一个例子,该底物是通过将β-酮酰胺互变异构化到亲电子卡宾中心形成的,以通过酰胺裂解实现异常环化。组合的实验和计算研究揭示了有利于异常环形成反应的机理途径,而不是一般的羰基叶立德中间体参与产物生成的机理。
