| Description |
Chiral Cr(III) salen complex 1 having t-Bu substituents at 3,3' and 5,5'-positions was used as a catalyst for the highly enantioselective aminolytic kinetic resolution (AKR) of racemic trans epoxides with different anilines as nucleophile in the presence of different ionic liquids at rt. Excellent yields (>98%) of anti beta-aminoalcohols with high enantioselectivity (ee >99%) was achieved in 4 h when [bmim]PF(6) was used as the ionic liquid. The present ionic liquid mediated AKR process is recyclable (up to six cycles with no loss in performance) and is five times quicker than the homogeneous process utilizing conventional organic solvents.
