Abstract

Direct interaction of salicylaldehyde oxyanion with ethyl 7-chloro-8-nitro-4-oxoquinoline-3carboxylate (2) delivered the respective 7-(2-formyl-phenoxy)-8-nitro-4-oxoquinoline-3-carboxylic ester 3. Reductive cyclization of 3 furnished the corresponding 4-oxo-[1,4]benzoxazepino[2,3h]quinoline-3-carboxylic ester 5. Acid-catalyzed hydrolysis of the esters 3/5… (More)
