Wang, Hung-Kai; Chio, Yu-Lun; Pallikonda, Gangaram; Wu, Hsyueh-Liang; Su, Haw-Lih; Hsieh, Jen-Chieh published an article in 2020, the title of the article was Copper-catalyzed dual cyclization for the synthesis of quinindolines.Category: nitriles-buliding-blocks And the article contains the following content:
A synthetic approach to quinindoline derivatives I (R = H, F, CF3, OMe, ; R1 = H, F, Me, OMe, NMe2; R2 = H, F, CF3, OMe; R3 = H, F, Cl, Me, NMe2, N(n-C4H9)2, OMe; R4 = H; RR1 = R2R3 = -OCH2O-; R3R4 = -CH:CH-CH:CH-) by the Cu-catalyzed dual cyclization has been developed. This catalytic reaction is a practical method for the systematic synthesis of quinindoline core structure I, which contains a limited-step synthetic strategy and can tolerant a wide variety of substituents. In addition, the mechanistic study reveals that the reaction initiates from a Lewis acid accelerated addition of aniline to nitrile and provides the indole substructure, and then the subsequent Cu-catalyzed C-N coupling reaction furnishes the quinoline subunit and affords the quinindoline structure I. The experimental process involved the reaction of 2-(2-Nitro-4-(trifluoromethyl)phenyl)acetonitrile(cas: 13544-06-4).Category: nitriles-buliding-blocks
