Prof S.Sarveswari and her research group interested in the synthesis and exploring the medicinal and physical properties of 4-phenyl quinoline and other derivatives of quinoline. This book refers, the synthesis and unambiguous structural determination of the 4-phenyl quinoline derivatives. Through IR, NMR and X-ray crystallographic studies structure were assigned, currently the author and her research group involved in the studies like 2D NMR, NLO and fluorescence properties of the reported compounds.

Quinoline heterocycles found to have diverse biological activities and 3-functionalised quinolines are important intermediates for the synthesis of various quinoline derivatives. 3-acetyl-4-hydroxy-quinolin-2(1H)-one and 6-chloro-3-acetyl-4-phenyl-2-methyl quinoline were chosen as intermediates for the synthesis of some novel quinoline derivatives. In particular, only a few methods are available for the synthesis of 3-acetyl-4-hydroxy-quinolin-2(1H)-one, which involve either two step or multistep reaction protocols. In the present work, a rapid, efficient and one pot procedure for the synthesis of 3-acetyl-4-hydroxy-quinolin-2(1H)-ones has been developed both by conventional and microwave assisted synthesis. The 3-acetyl quinolines were converted into chalcones which in turn converted to quinoline-3-yl pyrazolines and quinoline-3-yl isoxazolines and a few into 3-(2, 4-substitutedstyryl)isoxazolo 4,5-c]quinolin-4(5H)-ones. These compounds were explored for their anti-microbial and cyctotoxicity studies.

Pyrazolones are traditionally synthesized by the reaction of -keto esters with hydrazine and its derivatives. To date, synthesis of these compounds have been somewhat limited by the available chemistry. The methods available in literature to synthesize -keto esters are suffers by the use of carbon dioxide and carbon monoxide sources in presence of Pd or transition metal catalysts, long reaction time, use of excess reagent, inconsistent yield, large quantity of by products (due to self Claisen condensation) and require tedious work up procedures to remove the same. Unfortunately the existing methods not produced the -ketoesters of heteroaryl compounds from the heteroaryl esters in good yield. These factors lead us to develop a simple, convenient method to synthesize -keto esters which in turn converted into their corresponding pyrazoles. The synthesis of -oxy/thio substituted -keto esters through cross-Claisen condensation which suffers by many draw-backs, also been improved by new methodology. The newly synthesized compounds were subjected to screen their biological activities and the results discussed."
