In most substrate syntheses the Z isomer is formed predominantly under thermodynamic control, due to hydrogen bonding between amido and carboxyl group.

note
-
It should be noted that the remarkable results reported by Gridnev and Imamoto were mainly achieved at very low temperatures, which are in general not usual for enantioselective hydrogenations. Therefore, a change of the mechanism at room temperature and under normal pressure cannot be ruled out. This is also recognized by the authors: "On the other hand, nothing speaks against the possibility of a direct hydrogenation of [the substrate complex]."; ref. [18b]).

note

2 uptake for 5.0 mmol substrate (depicted in Figure 3) is so fast that especially in the initial stage, influence of diffusion cannot be excluded.

-
note
-
This effect is interpreted by the assumption that intermolecular exchange between diastereomeric substrate-catalyst complexes is "frozen" with decreasing temperature, which can be confirmed by comparison of relevant activation values for the oxidative addition of hydrogen and the retro conversion of the catalyst-substrate complexes into the starting compounds. These effects cause a disturbance in the additional delivery of the more reactive minor complex.
