OPTICALLY ACTIVE 2,2'-BIPHENOL DERIVATIVE AND METHOD FOR PRODUCING THE SAME

摘要

Disclosed are an optically active 2,2'-biphenol derivative and a method which enables simple and efficient production of the compound. Specifically disclosed are an optically active biphenol derivative represented by Formula (1) or (2); a method for optical resolution of a biphenol derivative represented by Formula (2'); a method for producing an optically active biphenol derivative (1) comprising a step of reacting a biphenol derivative (2) with a Brfnsted acid; and a method for producing an optically active biphenol derivative (3) comprising a step of reacting an optically active biphenol derivative (1) or an optically active biphenol derivative (2) with a Lewis acid. In the Formulae, R1 represents a primary or secondary alkyl group having 1-10 carbon atoms or the like; * represents an axial asymmetry center; X represents a halogen atom; and R2 represents a tertiary alkyl group having 4-6 carbon atoms.
