The palladium-catalyzedreaction of acetyl oximes with isocyanides was developed for the synthesis of 2H-pyrrol-2-imines. The key steps were (i) generation of an enamido-palladium(II) species, (ii) migratory double-isocyanide insertion, and (iii) cyclization. The scope of the synthesis of some 2H-pyrrol-2-imines was extended to the synthesis 1H-pyrrole-2,3-dione/1H-benzo[g]indole-2,3-dione derivatives
开发了钯肟基乙酰肟与异氰酸酯的反应,用于合成2 H-吡咯-2-亚胺。关键步骤是(i)生成烯胺基钯(II)物种;(ii)迁移性双异氰酸酯插入;以及(iii)环化。某些2 H-吡咯-2-亚胺的合成范围通过酸水解在1 H-吡咯-2,3-二酮/ 1 H-苯并[ g ]吲哚-2,3-二酮衍生物上得到扩展。顺序一锅法。
