NaBH4-CuCl/EtOH体系对α,β-不饱和酰胺选择还原
Selective Reduction of α,β-Unsaturated Amides with NaBH4-CuCl/EtOH
【摘要】 用NaBH4-CuCl/EtOH体系高选择地还原了α,β-不饱和酰胺的碳碳双键,考察了还原剂NaBH4和CuCl的用量、溶剂、不同的卤化物等因素对反应的影响.产物的结构经IR,1 H-NMR和元素分析等证实.该方法具有反应速度快(30min)、操作简便、试剂价廉易得等优点.
【Abstract】 A reducing system,NaBH4-CuCl/EtOH,are applied for the selective reduction of carbon-carbon double bond of α,β-unsaturated amides with high selectivity.Effects of the amount of NaBH4 and CuCl,solvent,different halide on the reaction have been investigated.The structure of products is characterized by IR,1H-NMR and elemental analysis.This method only requires inexpensive reagents,simple instruments,and a short reaction time(30 minutes).
