摘要

Abstract Fries rearrangement of 2-, 3-and 4-methoxyphenyl 3-methylbut-2-enoates 3-5 in methanesulfonic acid, polyphosphoric acid, aluminum chloride and under photochemical conditions have been studied. The outcome of the reactions was determined by the substitution pattern in the starting products and the reaction conditions used. Under Lewis acid catalysis, acylation accounted for the major components of the reaction mixtures, ...
