摘要：
Disclosed herein are optically active biphenol derivatives represented by the following formulas (1) and (2), a method for optically resolving a biphenol derivative represented by formula (2′), a production method of an optically active biphenol derivative (1) comprising a step for reacting a Brønsted acid with a biphenol derivative (2), and a production method of an optically active biphenol derivative (3) comprising a step for reacting a Lewis acid with an optically active biphenol derivative (1) or an optically active biphenol derivative (2).
