摘要

Effects of Hydrogen Pressure on the Stereoselectivity. Although homogeneous asymmetric hydrogenation of dehydroamino acids has been extensively studied,'little attention has been focused on the pressure dependency of stereoselectivity in these reactions. 2a Accordingly, we carried out the asymmetric hydrogenation of (2)-a-benzamidocinnamic acid (I),(2)-a- (acetamid0) cinnamic acid (2), methyl (2)-a-(acetamidolcinnamate (3), a-(acetamido) ...
