Photochemical synthesis of substituted furo-bis-quinolones

Continuing our work on the photochemical cyclization of furoic acid anilides, we prepared p-chloro and p-methoxy substituted dianilides of 3, 4-furandicarboxylic acid.The prepared anilides were exposed to Uv light of high pressure mercury arch in methanolic solution and under the strong stam of aoir. After 25h of irradiation it was possible to isolate substituted furo-bis-quinolones the substances with potential pharmacological activity.
