Title: Production of optically active 3-hydroxypyrrolidine
Inventor: ITO NORIKO
IPC: C07B57/00
Filed: 1991-07-29
Abstract: PURPOSE:To produce optically active 3-hydroxypyrrolidine by optically resolving easily available RS-3-hydroxypyrrolidine with an industrially easily available optically active tartaric acid anilide as a resolving agent. CONSTITUTION:RS-3-hydroxypyrrolidine (e.g. quantitatively obtained by reducing commercially available RS-N-benzyl-3-hydroxypyrrolidine in the presence of Pd/C catalyst) is optically resolved with an optically active tartaric acid anilide (both of the D and L isomers can be used) of the formula (R is chlorine or nitro) as a resolving agent to produce an optically active 3-hydroxypyrrolidine. The optically active tartaric acid anilide is obtained in a high yield e.g. by reacting tartaric acid with acetic anhydride, reacting the produced diacetyl tartaric acid anhydride with p-chloro or nitro-aniline and subsequently hydrolyzing the reaction product. The optically resolving agent is produced from inexpensive raw materials in a high yield, is chemically highly stable, can be recovered from a diastereomer salt solution in a high yield without being racemized, and can again be used.
