An efficient and facile method for the synthesis of a broad series of benzofurans and naphthofurans is described. The direct intramolecular cyclodehydration of aryloxyketones in the presence of titanium tetrachloride affords the corresponding benzofurans and naphthofurans with good regioselectivity and yields.

The reaction of 4-t-butyl-1,2-benzoquinone (9a), 4-methyl-1,2-benzoqinone (9b), and 1,2-benzoquinone (9c) with various enamines (10) and (11) are reported.Hydroxybenzodioxins (13) and (14) are isolated in most cases, and their conformational analyses are discussed.The reaction rates of 4-t-butyl-1,2-benzoquinone (9a) with the enamines (10a) and (10b) have been measured and an ionic mechanism is proposed.
