(b) For instance, the axial cyclohexanols are oxidized 3–6 times faster and esterified with anhydrides 2.5-3.8 times slower than the equatorial cyclohexanols; the axial esters are hydrolyzed 2.5 (p-nitrobenzoates) and 6.7 (acetates) times slower than the equatorial ones; the axial tosylates are displaced by nucleophiles 2.3-4.0 times faster, and the formation of diaxial dihalogenides with cholest-2-ene is 2.6 (Cl2) and 8.9 (Br2) times faster than the formation of diequatorial adducts.

This assumption is consistent with the wealth of data on the properties of the axial and equatorial bonds and on conformational equilibria of cyclohexane derivatives. 5 For a recent appraisal of the Baker-Nathan order problem, see also Edlund, U. Org. Magn. Reson. 1978, 11, 516. Coney, B. T.; Happer, D. A. R. Aust. J. Chem. 1987, 40, 1537; for a demonstration of the CC and CH hyperconjugation and the Baker-Nathan order in the ground state. The study of hyperconjugative involvement of the CC and CH bonds in the cyclohexyl carbonium ion system (Kirchen, R. P.; Ranganayakulu, K.; Sorensen, T. S. J. Am. Chem. Soc. 1987, 109, 7811) promises to provide a direct, clear-cut evidence of greater donor ability of the CH bonds. For a recent comment on CC and CH hyperconjugation in aldehydes, see: Laube, T.; Ha, T.-K. J. Am. Chem. Soc. 1988, 110, 5511. For a comparison of the Csp3-Csp2 and Csp3-h donor capabilities, see: Laube, T.; Stilz, H. U. J. Am. Chem. Soc. 1987, 109, 5876. Finally, as far as the ab initio calculations of the transition-state stabilities are concerned, the recent results obtained with the extended basis sets are consistent with the Cieplak model. 86a, 88

The 1,3 syn-diaxial interaction of the C(2)-CH3and C(6)-CH3methyl groups in 2, 2, 6,6-tetramethylpiperidine produces therefore a significant ring distortion (examination of the Cambridge Structural Database 1986 Version I reveals that the tetrahedral valency angle on the nitrogen found in piperidines is increased to the trigonal value in 2, 2, 6,6-tetramethylpiperidines, 122°, SD 4.6°, 62 entries). Since ionization potentials of amines and ethers are known to decrease when the ring size and the endocyclic valency angle increase (Yoshikawa, K.; Hashimoto, M.; Morishima, I. J. Am. Chem. Soc. 1974, 96, 288. Levy, G.; De Loth, P. C. R. Acad. Sci. Ser. C 1974, 279C, 331), this distortion seems to be the most likely reason for the extra decrease in the 2, 2, 6,6-tetramethylpiperidine case

As expected, electronegative substitution of the reagent reverses the preference for the less hindered approach in favor of the more hindered approach that is anti to the better a donor: Williamson, K.

Soc., Perkin Trans. 1 1974, 137, compare entries d-and g-j in Table I, p 138) but the replacement of Cl by S does not reverse the syn preference observed in cycloadditions of diazomethanes in this system and the reason for the discrepancy is not apparent: Landen, H.; Margraf, B.; Martin, H.-D.; Steigel, A. Tetrahedron Lett. 1988, 29, 6597. For another example of the anti approach to a better σ donor in cycloaddition reactions, see: Dolbier, W. R., Jr.; Wicks, G. E.; Burkholder, C. R. J. Org.

cs, see: Bernardi, F.; Bottoni, A.; Fossey, J.; Sorba, J. Tetrahedron 1986, 42, 5567. It is interesting to note that under these assumptions, the Cieplak model provides a simple rationalization of the increasing number of data on stereochemistry of cycloadditions to 5-substituted cyclopentadienes: Woodward, R.
