Stereoselective Addition of N-Alkylhydroxylamines to α,β-Unsaturated Nitro Compounds
收藏 引用
Chinese Chemical Letters 2006年 第7期17卷 859-862页
作者: Ai Jun LI Ji Cheng CHU Hong Sheng GUO Xue Qin ZHOU Dong Zhi LIU School of Chemical Engineering and Technology Tianjin University Tianjin 300072 Medical College Chinese People's Armed Police Force Tianjin 300071
N-Alkylhydroxylamines have been shown to undergo a stereospecific cis addition to 1-phenyl-2 -nitropropene compounds, whereas the corresponding O-alkylhydroxylamines give no diastereoselectivity. The concerted additio... 详细信息
