The first gold-catalyzed intermolecular coupling of alkynoates and allylic ethers invoking alkoxy addition and [3,3]-sigmatropic rearrangement as the key mechanism has been developed. Remarkably, the reaction showed complete chemoselectivity toward the pathway initiated by the alkoxy addition to alkynes. This unprecedented reactivity led to a new access to diversely substituted β-alkoxyacrylates in
已开发出第一个金催化的烷氧基化物和烯丙基醚的分子间偶联,其调用烷氧基加成和[3,3]-σ重排作为关键机理。显着地,该反应显示出对由烷氧基加成至炔烃引发的途径的完全化学选择性。这种空前的反应性使得人们可以高效地重新获得各种取代的β-烷氧基丙烯酸酯。
