چکیده انگلیسی
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 α,β-unsaturated alcohol was more than 99% with enantioselectivity up to 46%.
