Novel method for synthesis of unsymmetrical bis(indolyl)alkanes catalyzed by ceric ammonium nitrate (CAN) under ultrasonic irradiation
摘要:
The reaction of indole with (1H-indol-3-yl)(alkyl) methanol was catalyzed efficiently by ceric ammonium nitrate under ultrasonic irradiation to afford the unsymmetrical bis(indolyl)alkane in good to excellent yields. (c) 2005 Elsevier Ltd. All rights reserved.
