intermolecular [3 + 2] annulation pathway for aromatic acids with isocyanates to afford N-substituted phthalimide in one step is demonstrated, which provides an efficient process to direct preparation of phthalimide from commercially available starting materials and environmentally benign catalysts. This cascade cyclization involves the direct functionalization of an ortho C–H bond and the subsequent
一步一步证明了钌催化的芳香酸与异氰酸酯的分子间[3 + 2]环化路径,可在一步中得到N-取代的邻苯二甲酰亚胺,它提供了一种有效的方法,可从市售的起始原料和环境友好的催化剂中直接制备邻苯二甲酰亚胺。这种级联环化涉及邻C–H键的直接功能化以及随后的分子内亲核取代。除了在反应中产生水以外,没有理论上的浪费。
