Through the oxidative addition of cobalt into the N-C(O) bond of phthalimide and the subsequent decarbonylation, we describe an efficient cobalt-catalyzed intermolecular decarbonylative carboamidation of alkynes. High regioselectivities have been achieved for unsymmetrical alkynes (including aryl-alkyl or aryl-aryl) to deliver polysubstituted isoquinolones. To facilitate step economy, a three-component
通过氧化钴到邻苯二甲酰亚胺的NC(O)键中的氧化和随后的脱羰作用,我们描述了炔烃的有效钴催化的分子间脱羰碳酰胺化作用。对于不对称炔烃(包括芳基-烷基或芳基-芳基)可以实现高区域选择性,以递送多取代的异喹诺酮。为了促进步骤经济,目前的钴催化技术已证明炔烃与邻苯二甲酸酐和胺的三组分脱羰碳酰胺化反应。
