A copper-catalyzed [4+2] cyclization reaction of isoquinolines and alkynes is developed for the one-step construction of isoquinolinone derivatives with multisubstituted bridging rings. The unique feature of this three-component tandem cyclization reaction is the functionalization of the C1, N2, C3, and C4 positions of 3-haloisoquinolines via the construction of new C–N, C═O, and C–C bonds. This dearomatization
开发了一种铜催化的异喹啉和炔烃的[4+2]环化反应,用于一步构建具有多取代桥环的异喹啉酮衍生物。这种三组分串联环化反应的独特之处在于通过构建新的 C-N、C=O 和 C-C 键对 3-卤代异喹啉的 C1、N2、C3 和 C4 位进行官能化。这种用于合成结构复杂的异喹啉酮桥环状化合物的脱芳构化策略提供了良好的化学选择性、广泛的官能团相容性、绿色性和高步骤经济性。
