摘要

The heterogeneous selective hydrogenation of trans-4-phenyl-3-butene-2-one to allylic alcohol, catalyzed by Ir/SiO₂ stabilized with phosphines and modified by cinchona alkaloids, was described herein. Under the optimized conditions, the chemoselectivity to 伪,尾-unsaturated alcohol was more than 99%with enantioselectivity up to 46%.
