Abstract
The morpholine enamines of dihydroxyarylcyclohexanone, which were obtained by the reaction of p-benzoquinone, toluquinone, and phenyl-p-benzoquinone with the morpholine enamine of β-methylcyclohexanone, were converted by hydrochloric acid to hydroxytetrahydrobenzofurans. A method for the synthesis of substituted 2-hydroxydibenzofurans was developed by dehydration of the acetyl derivatives of the latter on heating with sulfur. Some transformations of the 2-hydroxydibenzofuran derivatives were studied.
