The gold-catalyzed cycloisomerization of enynyl esters bearing a cyclohexyl template has been studied and has been shown to lead to two types of products arising from 1,2- vs. 1,3-O-acyl-migration. Results have shown to be dependent on the nature of the solvent, the catalysts, the migrating group, the stereochemistry of the starting diastereomer as well as the alkene partner. This set of findings confirms
已经研究了带有环己基模板的烯丙基酯的金催化的环异构化,并显示出它们可导致由1,2- vs. 1,3- O-酰基迁移产生两种类型的产物。结果表明取决于溶剂的性质,催化剂,迁移基团,起始非对映异构体的立体化学以及烯烃配偶体。这组发现证实了乙酸炔丙酯的“金转盘”的复杂性质。
