report herein a catalyst‐free method to perform decarboxylative conjugated addition and hydrodecarboxylation of aliphatic N‐(acyloxy)phthalimides (redox active esters, RAEs) through photoactivation of electron‐donor‐acceptor (EDA) complex with Hantzsch ester (HE) in N,N‐dimethylacetamide (DMA) solution. The reactions present a green method to decarboxylatively construct carbon‐carbon bond and to perform
我们在此报告了一种无催化剂的方法,该方法通过将电子给体受体(EDA)与汉茨酯(HE)在N中进行光活化,来进行脂肪族N-(酰氧基)邻苯二甲酰亚胺(氧化还原活性酯,RAE)的脱羧共轭加成和加氢脱羧N-二甲基乙酰胺(DMA)溶液。该反应是一种绿色的方法,可以在温和的蓝光照射条件下,通过脱羧方式构建碳-碳键,并在较宽的底物范围和官能团耐受性下进行加氢脱羧反应,而无需借助常用的光氧化还原催化剂。
