Abstract
The synthesis of ethyl or methyl 6-substituted 3-(benzoylamino)-2-oxo-2H-pyran-5-carboxylates 2 and 3-(benzoylamino)-7,8-dihydro-2H-1-benzopyran-2,5(6H)-diones 4 by reaction of hippuric acid in acetic anhydride with ethyl or methyl 2-dimethylaminomethylene-3-oxoalkanoates and 2-dimethylaminomethylene-1,3-cyclohexanediones, respectively, is described. Some compounds 2 and 4 showed a strong local anesthetic activity in mice and a platelet antiaggregating activity in vitro comparable to that of acetylsalicylic acid, as well as moderate analgesic, antiinflammatory and antiarrhythmic activities in rats and mice.
