SYNTHESIS AND APPLICATION OF SOME NEW 5-SULFONYLHETEROCYCLO-8-QUINOLINOL DERIVATIVES
Hafez, Ali A. Abdel,Awad, Ibrahim M. A.
, p. 253 - 260 (2007/10/02)
A new series of 5-(4'-arylidene-3'-methyl-5'-oxo-4',5'-dihydropyrazol-1-yl-sulfonyl)-8-quinolinols (1a-e) were prepared via the reaction of 5-(3'-methyl-5'-oxo-4',5'-dihydropyrazol-1-yl-sulfonyl)-8-quinolinols with selected aldehydes.These compounds were
