本文报告八种新合成的1-苄基-3-酰胺基-4-取代苯基-2-吖丁啶酮(即β-内酰胺单环卫生物)的360兆核磁共振氢谱。本系列化合物均未见诸文献。利用偶合常数签定了β-内酰胺环的立体构型,并对整个系列的图谱进行了较详细的解析,证明所合成的化合物均为顺式构型的β-内酰胺单环卫生物。利用80兆核磁共振仪测定,未能获得必要的信息。 This paper reports the 360 ​​MeH NMR spectra of eight newly synthesized 1-benzyl-3-amido-4-substituted phenyl-2-azetidinones (ie, β-lactam monocyclic antibiotics). This series of compounds were not seen in the literature. The stereoconfiguration of β-lactam ring was confirmed by the coupling constant, and the whole series of spectra were analyzed in more detail. All of the synthesized compounds were proved to be β-lactam monocyclic hybrimers in cis configuration. The use of 80 trillion nuclear magnetic resonance measurement, failed to obtain the necessary information.
