摘要
It's a cinch! The title reaction with azomethine imines 1 uses an operationally simple procedure, based on the combination of the bromide salt of cinchona alkaloids (3) and KOH. The procedure is reliable and general. Trifluoromethyl-substituted amines can be accessed by a two-step deprotection of the product (S)-2. © 2009 Wiley-VCH Verlag GmbH & Co. KGaA.
