    • note
    • Because these calculations were performed with PCM, these enthalpies and energies formally contain solvation free energy corrections, so are not purely enthalpies or energies. More precisely, by "relative enthalpies" we mean the sum of electronic energies plus zero-point vibrational energies, thermal corrections, and solvation free energy corrections, without entropic corrections. "Relative energies" refer to electronic energies plus solvation free energies.

    • As noted above, for catalysts 7a-7c and 8, ee predictions require the computation of 40 TS structures.

    • note
    • Some of these TS structures were not geometrically viable due to severe steric congestion. In total, the data presented in Table 1 are based on 674 optimized TS structures.

    • note
    • One could envision various approaches to improve the efficiency of the above procedure. For example, currently, Hessians are explicitly computed preceding the unconstrained optimization in Step 5. However, we could instead project the normal modes from the reference TS onto an approximate Hessian.

    • note
    • Presently, the computation of some TS structures for some catalysts require human intervention. This is primarily the case in sterically conguested structures, for which AARON is not always able to construct reasonable starting TS structures.

    • For catalyst 8, the predicted ee based on relative free-energies is 6% ee (S), in conflict with the experimentally observed 42% ee (R).
