English Abstract

Imide (R, R) 1-benzyl-2, 5 dioxo-3, 4-dihydroxy-pyrrolidine was reduced by NaBH4/I2, NaBH4/BF3 under argon atmosphere at 0℃, and by LiAlH4 under argon atmosphere at 35℃ separately. Thus the corresponding tertiary amide (S, S) 1-benzyl-3, 4-dihydroxy-pyrrolidine was produced, and the yield was 63%, 58% and 66%. The melting point of each product was measured and the structure characterized by infrared spectroscopy. The reduction mechanism of diborane and LiAlH4 was finally discussed.
