Abstract
Substituted 5-hydroxy-2,3-dihydrobenzofuran and analogs such as the substituted 6-hydroxy-2,3-dihydrobenzopyrans were prepared from an appropriately substituted (5-hydroxy-2,3-dihydrobenzofuran-6-yl) formaldehyde or analog thereof with an aryl amine followed by reduction. These compounds were found to be potent topical anti-inflammatory agents.
