几个Aldol反应产物的NMR研究

NMR Studies on Some Aldol Reaction Products

利用1HNMR、13 CNMR、DEPT等一维谱和1H - 1HCOSY、HSQC、HMBC及1H - 1HNOESY等二维核磁共振波谱技术确定了 5种Aldol反应产物的结构 ,并对其1H、13 CNMR信号进行了全归属 ,初步探讨了取代基位置对化学位移的影响 .

The structures of 5 aldol reaction products were determined by 1D NMR spectroscopy(~1 H NMR、^(13) C NMR、DEPT) and 2D NMR spectroscopy (~1 H-~1 H COSY、HSQC、HMBC、~1 H-~1 H NOESY). All the ~1 H and ^(13) C NMR data were assigned, and the varieties of chemical shifts with the position of the substitute of the compounds were discussed.
