摘要: 本文提供了三类(六个)代表性四氢β-咔啉化合物的2D-NMR的同核二维相关谱(cosy)和同核NOE谱(NOESY)。根据实验测得的分子中有关基团间显示的NOE关系,指定了所有化合物的构型。借助分子模型,讨论了它们的构象。

Abstract: L-Tryptophanc methyl ester reacts with corresponding monoacetal of malonaldchydc under Pictct-Spenglcr conditions followed by Michael additions of methyl vinyl ketone to give diastereoisomcrs of tetrahydro-β-carbolines la,b, 2a,b and 3a,b. Their COSY and NOESY 2D-NMR spectroscopy were studied here. It was shown that in 1a, 2a, and 3a, there were NOE relationships between 3-H and 3'-H, in lb, 2b, and 3b however there were NOE relationships between OCH3 and CO2CH3 (for lb and 2b) or between 5'-CH3 and CO2CH3 (for 3b). Based on the results of NOE and the help of Dreiding Stereomodels their conformations were discussed.
