N-芳基-4-(N-苯甲酰基)亚胺基-5-异丙叉基噁唑烷-2-酮的合成及其波谱表征

Synthesis and spectral characterization of N-aryl-4-(N-benzyl)imine-5-isopropyloxaz-2-one

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

N aryl 4 imino 5 isopropyloxaz 2 ones are benzylized to get N aryl 4 (N benzyl)imino 5 isopro pyloxza 2 ones.The structures of them were identified by 1HNMR and CI MS.The products are inflexible molecules and the related protons locate in either in the shielded or deshielded area of the benzyl.Therefore,the chemical shifts of these protons change in different degree.
