excellent yields and high regioselectivity. The synthetic application of new protocol was extended to the synthesis of known tricyclic drug doxepin as well as a small library of oxepin based derivatives. For the first time, the obtained dibenzo[b,e]oxepinone derivatives were evaluated for their biological activities on the free-living nematode Caenorhabditis elegans as an effective and cost-efficient model
Abstract Friedel–Crafts cyclization products were obtained using 1.1 equivalents of environmentally benign trichloroacetic anhydride as sole reagent and solvent. The resulting ketones included benzothiepins, benzothiopyrans, benzoxepins, dibenzothiepins, dibenzoxepins, and tetralones.
Synthesis and Biological Activity of 11-(4-(Cinnamyl)-1-piperazinyl)-6,11-dihydrodibenz(b,e)oxepin Derivatives, Potential Agents for the Treatment of Cerebrovascular Disorders.
A series of 11-[4-(cinnamyl)-1-piperazinyl]-6, 11-dihydrodibenz[b, e]oxepins and related compounds were synthesized and evaluated for their protective activities against complete ischemia, normobaric hypoxia, lipidperoxidation and convulsion. Structure-activity relationship studies of this series led to the finding of (E)-1-(3-fluoro-6, 11-dihydrodibenz[b, e]oxepin-11-yl)-4-(3-phenyl-2-propenyl)piperazine dimaleate (50), AJ-3941 with the most appropriate property for combined pharmacological activities.
