Structure Elucidation of Clindamycin Phosphate by NMR Spectroscopy
克林霉素磷酸酯的波谱学研究

Clindamycin phosphate, an antibiotic drug, was used extensively in clinic. In this study, the 1H, 13C and 31P chemical shifts of the compound were assigned using 2D NMR techniques, including DEPT, 1H-1H COSY, 13C-1H HSQC and 13C-1H HMBC. The relative stereochemistry was established by the results obtained from quantum chemical calculation and NOESY spectroscopy. The fragmentation pathway of clindamycin phosphate was also analyzed by TOF-MS/MS.
