partial C–Cl bond reduction represents an important strategy for the construction of valuable chlorine-containing skeletons. Herein, we report an efficient and straightforward mono-(deutero)hydrodechlorination strategy of various trichloroacetyl esters and amides for the incorporation of gem-dichloromethyl moieties. The proposed mechanism involves key electron donor–acceptor (EDA) complexes formed between
选择性部分C-Cl键还原是构建有价值的含氯骨架的重要策略。在此,我们报告了各种三氯乙酰酯和酰胺的有效且简单的单(氘)氢脱氯策略,用于掺入偕二氯甲基部分。所提出的机制涉及催化环己硫醇(CySH)和底物之间形成的关键电子供体-受体(EDA)复合物,该复合物在蓝光照射下经历单电子转移(SET)过程,提供宝石-二氯自由基阴离子和CyS˙。克级反应和生物活性分子的后期修饰进一步证明了该方法的潜在效用。
