procedure for doublecarbonylation of o-dibromobenzenes with various 2-amino pyridines and naturally occurring amines, thus providing in good to excellent yields N-substituted phthalimides by using this palladium-catalyzedcarbonylation procedure. Furthermore, for the first time we have applied the developed synthetic protocol for the synthesis of biologically active molecule thalidomide via a single step

efficient palladium-catalyzed carbonylative cyclization of N-substituted 2-iodobenzamides and 2-iodoanilides was investigated for the synthesis of phthalimides and benzoxazinones, respectively, by usingphenylformate as a CO source. The present catalytic protocol circumvents the use of an expensive phosphine ligand as well as solvent in the case of the phthalimidesynthesis. Moreover, mild reaction conditions
通过使用甲酸苯酯作为 CO 源,研究了一种简单有效的钯催化的 N-取代 2-碘苯甲酰胺和 2-碘苯胺的羰基化环化反应,分别用于合成邻苯二甲酰亚胺和苯并嗪酮。本催化协议在邻苯二甲酰亚胺合成的情况下避免使用昂贵的膦配体以及溶剂。此外,温和的反应条件和对各种官能团的耐受性增强了该方法的普遍适用性。
