Abstract
An unusual Brønsted acid catalyzed cascade reaction of 2-[(2-aminophenyl)ethynyl]phenylamine derivatives with aryl(heteroaryl)aldehydes to afford an efficient alternative entry into 2,2′-disubstituted-1H, 1′H-3,3′-biindoles under metal-free conditions is reported. © 2014 American Chemical SocietyFile in questo prodotto:
