e) for the esterification of primary alcohols, secondary alcohols such as menthol undergo elimination. Evidence is presented to show that this unexpected result is due to the presence of trialkylammonium triflate salts. Such salts lead to a dramatic decrease in the rate of esterification relative to competing elimination. The Mitsunobu esterification of menthol with p-nitrobenzoic acid was re-examined

(−)-piperitone (3), (−)-carvenone (4), and (+)-pulegone (5), were examined by means of the temperature-dependent circular dichroism (CD) in the region of the n-π* transition. In polar solvents, the simultaneous occurrence of the conformational equilibrium and the asymmetric solvation was observed markedly for the compound 1 of these compounds, along with a change in the large rotational strength at lower temperatures
