Low-temperature oxidation of the four possible regioisomeric methoxy-substituted benzofurans 1 by dimethyldioxirane afforded the rather labile epoxides 2, which are in equilibrium with their equally labile quinone methides 3 through reversible valence iso
Preparation of 2H-Benzoxetes by Photoinduced Cycloaddition of Quinone Methides, Accessible by Dimethyldioxirane (DMD) Oxidation of 2,3-Dimethylbenzofurans

Irradiation (λ > 366 nm) of the quinone methides 3, which were formed by valence isomerization of the methyl-, chloro-, and tert-butyl-substituted 2,3-dimethylbenzofuran epoxides 2, afforded the novel 2H-benzoxetes 4 by photochemical cycloaddition.T
