A tetracyclic benzimidazole derivative of Kemp's triacid

Craig J Matthews, Sarah L Heath, William Clegg, Joyce C Lockhart

    Research output: Contribution to journalArticlepeer-review


    Fusion of Kemp's triacid with o-phenylenediamine produced a unique tetracyclic compd., identified structurally by X-ray crystallog. and soln. NMR spectroscopy, having one of the original carboxylic groups free, one forming a benzimidazole unit, which itself forms an amide with the remaining carboxylic group. [on SciFinder(R)]
