Herein, we report the decarboxylative Minisci heteroarylation of bicyclo[1.1.1]pentane (BCP) and 2-oxabicyclo[2.1.1]hexane (oBCH) derivatives at the bridge positions. In an operationally simple, photocatalyst-free process, free bridge carboxylic acids are directly coupled with nonprefunctionalized heteroarenes to provide rare examples of polysubstituted BCP and oBCH derivatives in synthetically useful
在此,我们报告了双环 [1.1.1] 戊烷 (BCP) 和 2-氧杂双环 [2.1.1] 己烷 (oBCH) 衍生物在桥位的脱羧 Minisci 杂芳基化。在操作简单、无光催化剂的过程中,游离桥羧酸与非预官能化杂芳烃直接偶联,以合成有用的收率提供罕见的多取代 BCP 和 oBCH 衍生物实例。此外,还评估了BCP 核心对代表性实例的物理化学性质的影响,与其全芳族邻位和间位取代类似物相比。
