摘要

Abstract Dimethyl 2-(formylmethyl) butanedioate (2e) has been synthesized regioselectively with an enantiomeric excess of more than 82% by the homogeneous catalytic hydroformylation of dimethyl itaconate (1e) with PtCl (SnCl 3)[(R, R)-DIOP] as the catalyst precursor. Under the conditions used a competitive hydrogenation to dimethyl 2- methylsuccinate (3e) takes place. This reaction occurs with an optical yield of up to 51%. ...
