摘要
(Chemical Equation Presented) A highly enantioselective synthesis of aryl glycine derivatives from asymmetric hydrogenation was achieved by subjecting N-PMP-protected α-aryl imino esters to hydrogenation under Rh-bisphosphine catalysis (see scheme; PMP = para-methoxyphenyl, cod = cycloocta-1,5-diene). The PMP group could be easily removed for the preparation of enantiomerically pure aryl glycine derivatives. © 2006 Wiley-VCH Verlag GmbH & Co. KGaA.
