Unusual thermal rearrangement of the endo-peroxides of 2,5-dimethylfurans
Abstract
Thermal rearrangement of the endo-peroxides of the 2,5-dimethylfurans (1b) and (1c) in refluxing benzene leads to the corresponding diepoxides (4b) and (4c), which provides a convenient entry to the synthesis of these compounds which are structurally related to crotepoxide.
