摘要: 应用DEPT(无畸变极化转移增强谱)、HMQC(异核多量子相干谱)、HMBC(异核多键相干谱)、1H-1H COSY(相关谱)、NOESY(核欧沃豪斯谱)和 TOCSY(全相关谱)谱学技术,对泰妥拉唑所有的氢进行了归属. 不对称硫原子引起邻接CH2 2个氢化学位移不等价;该2个氢相互偶合,其偶合常数为12.9 Hz;借助DEPT谱,2个甲氧基被区别;借助DEPT和TOCSY谱,另2个与碳相连的甲基被区分;利用HMBC谱,所有的碳峰可以归属. 

Abstract: Tenatoprazole is a novel proton pump inhibitor currently undergoing phase III clinical trail. In this study, the 1H and 13C chemical shifts of this compound were assigned using 2D NMR techniques, including DEPT, HMQC, HMBC, COSY, NOESY and TOCSY. The asymmetric structure of the compound was elucidated by NOESY. All quaternary carbons of the compound were also assigned by HMBC.
