An unprecedented enantioselectiveoxetaneopening with chloride provides access to a range of highly functionalized three‐carbon building blocks. The excellent enantiocontrol is enabled not only by a new catalyst, but also by the unusualuse of wetmolecularsieves for the controlledrelease of HCl.

Identification of an electron poor trifluoroacetophenone allows the formation of uniquely stable hemiketals from prochiral oxetanols. When exposed to a cobalt(II) catalyst, efficient ring-opening to densely functionalized dioxolanes is observed. Mechanistic studies suggest an unprecedented redox process between the cobalt(II) catalyst and the hemiketal that initiates the oxetane-opening. Based on this observation
鉴定缺电子三氟苯乙酮可以从前手性氧杂环丁醇中形成独特稳定的半缩酮。当暴露于钴 ( II ) 催化剂时,观察到致密官能化二氧戊环的有效开环。机理研究表明,钴 ( II ) 催化剂和引发氧杂环丁烷开环的半缩酮之间存在前所未有的氧化还原过程。基于这一观察,探索了瞬态半缩酮的动态动力学分辨率,该分辨率使用 Katsuki 型配体进行立体感应(高达 99 : 1 dr 和 96 : 4 er)并允许访问各种 1,3-二氧戊环(20 个示例,产率高达 98%)。
