It is not unexpected that the methoxyl substituent on a cyclohexane ring
prefers to adopt the equatorial conformation.

What is unexpected is that the closely related 2-methoxytetrahydropyran
prefers the axial conformation:

H
OMe
OMe
A Gp=-0.6 kcal/mol
Methoxy: CH3O group
Please be specific and clearly write the reason why this is observed. This effect that provides
stabilization of the axial OCH 3 group in this molecule is called the anomeric effect. [Recall in the way of
example, the staggered conformer of ethane is more stable than eclipsed owing to bonding MO
interacting with anti-bonding MO...]
