    • 13C resonances associated with the C=O of the phthalimide group were not easily observable in several of the cycloadducts in which this moiety occupied the equatorial position. (The exception to this observation is compound 15b.) All other analytical data obtained on these equatorial diastereomers were consistent with their assigned structure.

    • This is the first published example of the reaction of an oxyallyl cation with this oxygenated diene. This process, however, is not particular to the nitrogen-substituted species 1. For example, Lautens has observed the cycloaddition of 2-methoxyfuran with a dialkyl-substituted oxyallyl cation. (Lautens, M. Personal communication, University of Toronto.
