摘要
L-苯丙氨酸和硬酯酰氯经酯化、酰胺化、皂化和酰氯化反应得到新型手性固定相,用FTIR、1HNMR和元素分析对手性固定相(CSP)进行了表征。将制得的手性固定相按m(CSP)∶m(硅胶)=3∶1制备薄层色谱板,采用V(乙醇)∶V(乙酸乙酯)∶V(三乙胺)=11∶5∶1作为展开体系,对手性药物度洛西汀进行拆分,其中右旋度洛西汀Rf1=0.87,左旋度洛西汀Rf2=0.75。
L-Phenylalanine CSP was prepared from L-phenylalanine and stearoyl chloride via esterifieation, amidation, saponification and acid chloride reaction. The CSP was characterized by means of FTIR, 1HNMR spectra and elemental analysis. Thin layer chromatography was prepared from the CSP and silica gel based on a mass ratio of 3 : 1. Using the development system of V(ethanol) : V ( ethyl acetate) : V(triethylamine) = 11:5:1, duloxetine was separated on the TLC, with (R) -duloxetine Rfl = 0.87, (S) -duloxetine Rf2 = 0.75.
