Enantiomerically pure 1,2-bis(isopropylmethylphosphino)benzene and its use in highly enantioselective Rh-catalyzed asymmetric hydrogenation

Add time:07/24/2019    Source:sciencedirect.com

A new P-chiral phosphine ligand with a 1,2-phenylene unit, (S,S)-1,2-bis(isopropylmethylphosphino)benzene, has been synthesized from 1,2-bis(methylphosphino)benzene. Its rhodium complex is highly effective in asymmetric hydrogenation of dehydroamino acid methyl esters to provide enantioselectivities of up to 98%.
