A novel and efficient method has been developed for the chemoselective conjugate reduction of α,β-unsaturated ketones with tosylhydrazine as a hydrogen source to the corresponding saturated ketones in moderate to good yields. The present protocol does not require the use of transition metal, and is efficient being applicable to a wide range of substrates (25 examples).
已开发出一种新颖有效的方法,以甲苯磺酰肼为氢源,将α,β-不饱和酮化学选择性共轭还原为相应的饱和酮,产率中等至良好。本协议不需要使用过渡金属,并且有效地适用于广泛的衬底(25个示例)。
