双环[1.1.1]戊烷(BCP)作为一种具有三维立体结构的桥环骨架, 因其可作为苯环、叔丁基及炔烃等基团的生物电子等排体, 已在药物化学领域得到广泛应用. 目前, 通过[1.1.1]螺桨烷的自由基开环反应, 已成为构建BCP衍生物最常用的策略. 传统[1.1.1]螺桨烷自由基官能团化反应的条件苛刻, 官能团兼容性较差. 近年来, 随着光催化在有机合成中的迅速发展, 多种光催化的[1.1.1]螺桨烷官能团化策略相继被报道, 并被成功应用于药物分子的合成. 对基于自由基途径的[1.1.1]螺桨烷官能化研究进展进行简要综述.

Bicyclo[1.1.1]pentane (BCP), a three-dimensional bridged ring scaffold, has been widely used in medicinal chemistry due to its role as a bioisostere for groups such as benzene rings, tert-butyl groups, and alkynes. Currently, the radical ring-opening reaction of [1.1.1]propellane has become the most common strategy for constructing BCP derivatives. Traditional radical functionalization of [1.1.1]propellane typically requires harsh conditions and exhibits poor functional group compatibility. In recent years, with the rapid development of photocatalysis in organic synthesis, various photocatalytic functionalizations of [1.1.1]propellane have been reported and successfully applied in the synthesis of drug molecules. Herein, a concise overview of recent advances in radical-based functionalization of [1.1.1]propellane is provided.
Key words: 1.1.1]propellane; bicyclo[1.1.1]pentane; radical; photocatalysis; functionalization
