At the beginning of the work, we supposed that discrimination between the two oxygen atoms depends on the stability of the cationic intermediates from intramolecular bromoetherification. (See ref. [5], where the direction of discrimination expected from the activation energy is the same as the direction from the stability of the cationic intermediates.) Later, during the work on optical resolution (ref. [6]), the obtained direction was found to be opposite to the direction expected from the stability of the cation intermediates, but the same as the order of activation energies. We therefore suppose that the genuine factor for discrimination of the two oxygen atoms of the acetal is the difference in the activation energies of the transition states.

Compound 7a is stable when it stands at room temperature although it has an aldehyde functionionality. Its stability may depend on its crystallization at room temperature, although other norbornene aldehydes, such as 1a, 1b, and 7b, are oils and need refrigeration for prolonged storage.
