A radical-based, photo-catalyzed decarboxylative formation of stereodefined tri- and tetrasubstituted olefins is reported using various α-amino radical precursors and heterocycles as substrates. This user-friendly protocol combines a wide structural scope, easy drug and postsynthetic manipulations, and variation in both reaction partners. The mechanistic studies reveal a key CO2 extrusion step to enable
据报道,使用各种α-
氨基自由基前体和杂环作为底物,基于自由基的光催化脱羧形成立体定义的三取代和四取代烯烃。这种用户友好的方案结合了广泛的结构范围、简单的药物和合成后操作以及两种反应伙伴的变化。机理研究揭示了实现整体转变的关键CO 2挤出步骤。
