(3S,4S)-N-benzyl-3,4-dihydroxy pyrrolidine was synthesized using NaBH4/I2 as the reducing agent in THF.The effect of the molar ratio of the starting materials,the reaction time,and the type of reducting agents were explored.Under the optimum condition,i.e.,the molar ratio of substrate to NaBH4 and I2 was 1:5:1.67,and the refluxing reaction time was 6 h,the yield was up to 70%.The product was charac-terized by 1H and 13C NMR spectroscopy,and all the results were consistent with the compounds synthesized. Compared with the conventional synthetic method,the method has such advantages as inexpensive reagents, simple operation,and easy scaling up.
