Asymmetric hydrogenation of β - methylcinnamates of phenylalkylmethanols. Catalyst-phenyl groups interactions in the preferred adsorption conformation

The β-methylcinnamates of four S-alkylphenylmethanols have been hydrogenated on Pt catalyst. The observed asymmetric inductions suggest that simultaneous bonded interactions of both the phenyl groups with the catalyst in the transition states do not occur.
