A series of quinoline derivatives have been elaborated from reaction of 2-(
m
- and
p
-acetylanilino)-quinolines 6a–b with
aldehydes under Claisen-Schmidt conditions followed by cyclization with phenyl hydrazine and hydroxylamine. Reaction of 6a and
6b with hydrazine, semicarbazide and thiosemicarbazide, cyanoacetylhydrazide and some subsequent condensation reactions led to
diverse quinoline derivatives. Anti-Aphid
Aphis gossypii
that harm cotton crop in Egypt was screened. Compound 12 showed an LC
50
value of 19429E-10 ppm which is much more active than Marshal (Carbosulfan), one of the broad spectrum insecticides widely used
in this field
CONFLICT OF INTEREST
The authors have declared that no conflict of interests exist.
