butyrolactams has been enabled by photoredox catalysis through a reductive radical–polar crossover mechanism. This mechanism operates with precision on unactivated aromatic substrates to give a wide range of 1,4-hydroalkylation products. This method utilizes a simple organic catalyst/reductant pair to deliver products in a highly flexible manner with respect to substitution, and the products can be
线性酰胺的脱芳香环化为复杂的螺环丁内酰胺是通过光氧化还原催化通过还原自由基-极性交叉机制实现的。该机制在未活化的芳香族底物上精确运行,产生多种 1,4-加氢烷基化产物。该方法利用简单的有机催化剂/还原剂对以高度灵活的取代方式提供产物,并且产物可以在简单的条件下进一步功能化以提供图案集合。这里进行的机理分析概述了该策略的显着特征,该策略被应用于制备一系列复杂的支架,包括抗惊厥剂加巴喷丁。
