This proceedings volume contains selected papers that were
presented in the 3rd International Symposium on Big data and Cloud
Computing Challenges, 2016 held at VIT University, India on March
10 and 11. New research issues, challenges and opportunities
shaping the future agenda in the field of Big Data and Cloud
Computing are identified and presented throughout the book, which
is intended for researchers, scholars, students, software
developers and practitioners working at the forefront in their
field. This book acts as a platform for exchanging ideas, setting
questions for discussion, and sharing the experience in Big Data
and Cloud Computing domain.
The book presents papers from the 6th International Conference on
Big Data and Cloud Computing Challenges (ICBCC 2019), held at the
University of Missouri, Kansas City, USA, on September 9 and 10,
2019 and organized in collaboration with VIT Chennai. The book
includes high-quality, original research on various aspects of big
data and cloud computing, offering perspectives from the industrial
and research communities on how to address the current challenges
in the field. As such it is a valuable reference resource for
researchers and practitioners in academia and industry.

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."
