由 N-芳基 - 4 -亚胺基 - 5 -异丙叉基唑烷 - 2 -酮苯甲酰化制得 N-芳基 - 4 - (N-苯甲酰基 )亚胺基 - 5 -异丙叉基唑烷 - 2 -酮 ,其结构式得到了核磁共振波谱和质谱数据的确认。后者分子为刚性分子结构 ,相关质子分别处于苯甲酰基的屏蔽区和去屏蔽区 ,因而其 1 HNMR波谱发生了不同程度的化学位移变化
Synthesis of N - aryl - 4 - (N - benzoyl) imino - 5 from N - aryl - 4 - imino - 5 - isopropylideneoxazolidine - 2 - - isopropylidene - oxazolidine - 2 - one, its structure has been confirmed by nuclear magnetic resonance spectroscopy and mass spectrometry data. The latter molecule is a rigid molecular structure, the relevant protons are in the shielding and deprotection areas of benzoyl, respectively, and thus their 1 H NMR spectra undergo different degrees of chemical shifts
