A series of δ-alkoxy-substituted electron-deficient alkyneswere isomerized to the corresponding dienol ethers using phosphinecatalysis. Both Ph 3 P and a polymer-supported phosphine werefound to be useful in this context. This methodology representsa general procedure for the synthesis of ‘push-pull' δ-alkoxy dienones.
一系列 δ-烷氧基取代的缺电子炔烃使用膦催化异构化为相应的二烯醇醚。发现 Ph 3 P 和聚合物负载的膦在这方面都是有用的。这种方法代表了合成“推拉”δ-烷氧基二烯酮的一般程序。
