Process for the preparation of chiral 3-hydroxy pyrrolidine compound and derivatives thereof having high optical purity |
| abstract |
The present invention relates to an effective process for the preparation of optically pure chiral 3-hydroxypyrrolidine or derivatives thereof. More particularly, the present invention relates to an efficient process for the preparation of chiral 3-hydroxypyrrolidine or derivatives thereof, comprised of introducing a suitable protecting group to the starting material 4-chloro-3-hydroxybutyronitrile. Introduction of the hydroxy-protecting group provides advantages: efficient prevention of formation of side products, enhanced performance of the reduction of the nitrile group of the starting material, and enhanced performance of in-situ in¬ tramolecular cyclization. The chiral 3-hydroxypyrrolidine compound is produced in high yield and with high purity. |
