The absence of reactivity of imines towards Ruppert's reagent (CF3SiMe3) could be overcome by the addition of an auxiliary silylating agent to the reaction medium. Under these conditions variously substituted alpha-trifluoromethylated amines are readily obtained from the corresponding imines. (C) 1999 Published by Elsevier Science Ltd. All rights reserved.

Intramolecular Diels-Alder reactions of furan derivatives: Steric and electronic effects of trifluoromethyl groups
Intramolecular Diels-Alder reactions of furanderivatives each containing a trifluoromethyl group in the dienophilic part or the tethering chain of the dienophile to the furan ring showed a notable electronic effect of the trifluoromethyl group on the stereoselectivity. The electronic effect of the trifluoromethyl group was confirmed by results of a comparison with other substituents (phenyl, methyl
