Optically active maleimide derivative, an optically active polymaleimide derivative, its production method, method for separating optically active compounds using such a separating agent composed of the optically active polymaleimide derivative

摘要

PROBLEM TO BE SOLVED: To provide a new agent for separating an optical isomer, having high resolution ability.;SOLUTION: The optically active polymaleimide derivative represented by general formula (3) [wherein, for example, R₃-X₃, R₄-X₄, R₅-X₅ and R₆-X₆ are each a hydrogen atom, and R₁-X₁, R₂-X₂, R₇-X₇ and R₈-X₈ are each independently a hydrogen atom or a benzyl group (with the proviso that all of R₁-X₁, R₂-X₂, R₇-X₇ and R₈-X₈ are not the same substituent)] is used as the agent for separating the optically active compound.;COPYRIGHT: (C)2005,JPO&NCIPI
