    • Although the barrier could not be measured for these dendrons, we have recently measured a barrier of 12.3 kcal/mol in a related pyridine-2,6-diamide system using NMR line-shape analysis. This barrier most likely represents an upper limit for the dendrons and dendrimers described in this manuscript. Preston, A. J.; Fraenkel, G.; Chow, A.; Gallucci, J. C.; Parquette, J. R. J. Org.

    • We conclude that the decreased hydrogenation rate is due to catalyst poisoning rather than steric encumbrance for two reasons. (1) Hydrogenation is relatively slow even for first-generation dendron 1b. (2) These dendrons are known to efficiently coordinate to transition metals, see: Rauckhorst, M. R.; Wilson, P. J.; Hatcher, S. A.; Hadad, C. M.; Parquette, J. R. Tetrahedron 2003, 59, 3917.
