郭永沺等由莪术醇合成(艹卓)酮类化合物,进而合成出有明显降压作用的拟生物碱新化合物。其结晶性中间产物的结构确定对鉴定最终还原产物和合成、设计其它改性物十分重要。由元素分析和质谱数据确定了此未知物的分子式为C_(21)H_(28)NO;红外谱表明了酮基、异丙基、
Guo Yong Yong et al by Curcuma alcohol synthesis (艹 Zhuo) ketones, and then synthesized with obvious antihypertensive effect of the new alkaloid compounds. The structural determination of its crystalline intermediates is important for the identification of the final reduced product and for the synthesis and design of other modifications. The molecular formula of this unknowns was C 21 H 28 NO determined by elemental analysis and mass spectrometry data. The IR spectra showed that keto, iso-propyl,
