Trifluoromethanesulfonic acid-catalyzed solvent-free bisindolylation of trifluoromethyl ketones
摘要:
A trifluoromethanesulfonic acid-catalyzed solvent-free bisindolylation reaction of indoles with alkyl and aryl trifluoromethyl ketones has been developed. The trifluoromethyl-substituted bisindolylalkane derivatives were synthesized in moderate to excellent yields. (C) 2014 Elsevier Ltd. All rights reserved.
