three‐component coupling reactions between arynes, isocyanides, and either activated alkynes or phenyl esters generates unusual iminoindenones or phenoxy iminoisobenzofurans (see scheme), the latter of which may be advanced to o‐ketobenzamides by performing direct hydrolysis. The synthetic utility of these compounds is demonstrated in a rapid preparation of substituted dibenzoketocaprolactams.
三重冠:芳烃,异氰化物与活化的炔烃或苯酯之间的一对三组分偶联反应会生成不寻常的亚氨基茚满或苯氧基亚氨基异苯并呋喃(参见方案),后者可通过进行直接水解而发展为邻-酮基苯甲酰胺。这些化合物的合成效用已在快速制备取代的二苯并酮基丙内酰胺中得到了证明。
