8 the regio-preference was still 2:1 in the usual direction and may be suggestive of an additional electronic component from the ester carbonyl in 12. Furan, a very special enol ether type, undergoes the initial nitrone cycloaddition in the reversed sense to a monoadduct which then behaves as a typical enol ether to undergo a second nitrone addition in the usual regiochemical sense., and references therein.

The unwanted reaction of 9d → 15 is apparently an acid catalyzed reaction which is further aggravated by the use of more polar solvents Omission of an acid catalyst slows down the exchange reaction considerably and the lifetime of 9b is consequently extended Alternate routes to the nitrone 12d are being evaluated.

11 has suggested that favorable orbital interactions would arise when the carbon-oxygen bond is orthogonal to the nitrone in the transition state. The importance of such a rotamer in the present system is uncertain.
