| Abstract: | A reducing system,NaBH4-CuCl/CH3OH,was applied for the selective reduction of carbon-carbon double bond of α,β-unsaturated esters with high selectivity.Effects of the amount of NaBH4 and CuCl,solvent,different halide on the reaction were investigated.The structure of products was characterized by IR,1H-NMR and elementary analysis.The yield was verified by HPLC.This method only requires inexpensive reagents,simple instruments,and a short reaction time(10 minute). |
