[Synthesis and antibacterial activity of thiosemicarbazones of 3-acylquinolones].
Oxidation of 3-acetyl derivatives of 3-acetyl-1-ethyl-1,4-dihydro-6,7-methylenedioxyquinoline-4-one (VIc) and 3-acetyl-7-chloro-1-ethyl-6-fluoro-1,4-dihydroquinoline-4-one (VId) with selenium dioxide provided the corresponding acids, [1-ethyl-1,4-dihydro-6,7-methylenedioxy-4-oxoquinoline-3-yl]glyoxylic acid (VIe) and [7-chloro-1-ethyl-6-fluoro-1,4-dihydro-4-oxoquinoline-3-yl]glyoxylic acid (VIf), respectively. Reactions of compounds VIc--VIf with thiosemicarbazide yielded the respective thiosemicarbazones of 3-acetyl-1-ethyl-1,4-dihydro-6,7-methylenedioxyquinoline-4-one (VIIa), 3-acetyl-7-chloro-1-ethyl-6-fluoro-1,4-dihydroquinoline-4-one (VIIb), [1-ethyl-1,4-dihydro-6,7-methylenedioxy-4-oxoquinoline-3-yl]glyoxylic acids (VIId). The compounds showed no significant in vitro antibacterial activity.
