Yeni 8-hidroksi kinolin türevlerinin sentezi ve biyolojik aktivitelerinin incelenmesi

Quinoline is a very important class of heterocyclic compound that exhibits unique biological and pharmacological properties, as well as pyrazoles and imines. The aim of this master thesis is: Synthesis and characterization of some novel quinoline-containing Pyrazole and imine derivatives and investigation of their biological activities. For this purpose, Compound (51) was obtained in 89% yield using 8-hydroxy quinoline (2) and 2-bromopropanoate in the presence of base. The reaction of (51) with hydrazine hydrate, the targeted compound (52) was obtained in 77% yield. Cyclization of compound (52) with acetyl acetone or benzoyl acetone yielded compounds (55) and (57) in good yields. In addition, the synthesis of imine (53a-f) was performed as a result of the condensation of compound (52) with various aromatic aldehydes. The synthesized compounds were investigated for antimicrobial activity test against two types of bacteria. These species are Bacillus and Staphylococcus aureus.
