Abstract:
The objective of the present study was to synthesize a series of some novel quinoline based methoxy substituted chalcones and to evaluate their in vitro antimalarial, anti-inflammatory, antioxidant and antidiabetic activitites. The quinoline based chalcones was synthesized by condensation of 2-chloro-3-formyl qunoline with various methoxy substituted acetophenone in presence of NaOH. The Claisen-Schmidt condensation gave high yield of quinoline based chalcones. Synthesis of 2-chloro-3-formyl quinoline was carried out by Vilsmeir-Haack reaction on acetanilide and 4-methoxy acetanilide which on

Abstract:
Acetanilide is converted into 2-chloro-3-formyl quinoline by reacting with DMF-POCl3 at 80-90?C and then condensed with aromatic primary amines to give Schiff bases (3a-3c). These Schiff bases are then reacted with acid chlorides in the presence of base in toluene to give 1, 3, 4-substituted 2-azetidinones.
