Aromatization of arene 1,2-oxides. 1,2-Oxides of methyl phenylacetate and methyl trans-cinnamate

Article abstract of DOI:10.1021/jo00319a029

Substituent migration is observed only to a minor extent during aromatization of the 1,2-oxide of methyl phenylacetate to methyl (o-hydroxyphenyl)acetate; the major aromatization pathway does not involve substituent migration. Substituent migration is not observed during aromatization of the 1,2-oxide of methyl trans-cinnamate to methyl o-coumarate.
