The synthesis of N-unprotected isoindolinones via rhodium(III)-catalyzed intramolecular C(sp3)–H amidation of various 2-methyl-N-substituted benzamides is developed. This protocol employs a free amino acid l-alanine as a ligand, which could significantly increase the reactivity of rhodium catalyst.
开发了通过铑 (III) 催化的各种 2-甲基-N-取代苯甲酰胺的分子内 C(sp 3 )-H 酰胺化合成 N-未保护的异吲哚啉酮。该协议采用游离氨基酸l-丙氨酸作为配体,可显着提高铑催化剂的反应性。
