We report a direct CH alkylation of heteroarenes via photocatalytic decarboxylative couplings. A series of primary, secondary, tertiary alkyl carboxylic acids and drug-derived N-hydroxyphthalimide esters are selectively coupled with various electron-rich heteroarenes, including furans, benzofurans and thiophenes. With advantages of mild reaction conditions, broad scopes of substrates and easy handling
我们报告了通过光催化脱羧偶联对杂芳烃进行直接 C H 烷基化。一系列伯、仲、叔烷基羧酸和药物衍生的N-羟基邻苯二甲酰亚胺酯与各种富电子杂芳烃选择性偶联,包括呋喃、苯并呋喃和噻吩。这种转化具有反应条件温和、底物范围广、易于操作等优点,是一种有价值的有机合成方法。
