While not shown in Scheme 2B, all steps of the catalytic cycle could be
reversible.

[10] Deuterium labelling experiments clearly supported the intramolecular
nature of the hydride transfer step. See the SI for more details.

[12] The relative steric demands are evaluated on the basis of the A-values
for a phenyl group (2.8 kcal/mol) and a methyl group (1.74 kcal/mol).
For A-values of various substituents, see: E. L. Eliel, S. H. Wilen, M. P.
Doyle, Basic Organic Stereochemistry, Wiley, 2001, p. 444.
