The reaction of formyl imidazole (in the presence and absence of DABCO, and
with either THF or methanol as solvent) with alpha-hydroxylaryl derivative
s of methyl acrylate affords novel synthetic intermediates. By controlling
the reaction conditions, either allylic substitution products (THF, DABCO)
or rearrangement (MeOH, no DABCO) products result.
