1,2-BIS(DIALKYLPHOSPHINO)-4,5-(METHYLENEDIOXY)BENZENE DERIVATIVE, METHOD FOR MANUFACTURING SAME, METAL COMPLEX HAVING THIS 1,2-BIS(DIALKYLPHOSPHINO)-4,5-(METHYLENEDIOXY)BENZENE DERIVATIVE AS A LIGAND, AND ASYMMETRIC HYDROGENATION METHOD

摘要

Provided are a novel 1,2-bis(dialkylphosphino)-4,5-(methylenedioxy)benzene derivative that forms a metal complex having particularly high asymmetry induction capacity and catalytic activity on ß-dehydroamino acids, a method for manufacturing the same, a metal complex having this 1,2-bis(dialkylphosphino)-4,5-(methylenedioxy)benzene derivative as a ligand, and an asymmetric hydrogenation method using this metal complex. A 1,2-bis(dialkylphosphino)-4,5-(methylenedioxy)benzene derivative represented by general formula (1). (In the formula, R1 and R2 represent an alkyl group having 1-10 carbon atoms, and R1 and R2 have different numbers of carbon atoms.)
