-
Perusal of data in the literature indicates that the group attributed to M (medium size) is almost invariably an aliphatic one (bearing CHs); see Table 1 in: A. Mengel and O. Reiser, Chem. Rev., 1999, 99, 1191 entitled Around and Beyond Cram's Rule. This suggests that the CH/O hydrogen bond is working in stabilizing the preferred conformation.

-1, respectively, at the MP2/6-311G(d,p)//MP2/6-31G(d), MP2/6-311G(d,p)//MP2/6-311G(d,p) and MP4/6-311G(d,p)//MP2/6-31G(d) levels of approximation. Note that the above values are the difference in the potential energy barrier and not the Gibbs energy difference as reported in Table 6. See also ref. 17.
