isomerization/racemization catalyst gives rise to carbocyclic allylic esters with excellent stereoselectivity from readily available tertiary carbinols. An easy-to-use teabag setup combining resin-bound catalysts, a biphasic isooctane–water solvent system, and a highly lipophilic acyl donor efficiently suppresses side reactions and allows for the preparation of functionalized carbocyclic building blocks in high yields
一种基于酶酰化催化剂与异质布朗斯台德酸作为异构化/消旋催化剂之间相互作用的新型迁移动态动力学拆分,可从容易获得的叔甲醇中产生具有优异立体选择性的碳环烯丙基酯。一种易于使用的茶袋装置,结合了树脂结合的催化剂,两相异辛烷-水溶剂系统和高度亲脂性的酰基供体,可有效抑制副反应,并能够以高收率和光学纯度制备功能化的碳环结构单元。
