A major role in synthetic organic chemistry is played by organoboron compounds, among which arylboronic acids have come out in an important position. Arylboronic acids are very significant in modern organic chemistry, bioorganic, medicinal and materials chemistry. Arylboronic acids are mild Lewis acids which are usually stable and easy to handle, making them essential to organic synthesis. In our work, we studied the application of arylboronic acids as Lewis acid catalyst in the synthetic organic chemistry to synthesize some heterocycles and organic molecules.

This book includes the convenient and useful methods for the synthesis of Novel heterocycles and organic molecules and studied their anti-HIV NNRTI activity. In the second part of our work, we studied the concept of l-proline- thiaurea based bifunctional organicatalyst for Asymmetric Aldol reaction. Synthesis of Novel heterocycles such as oxochromenyl xanthenones, Chromeno-Chromenones, Thiazolidinones, Pyrazolothiazoles, triazolyl pyrimidinones, triazolyl phenyl thiazoles and Organocatalyst is neatly described. The aim of this book to provide guidelines to synthesize and improve the...

Organocatalysis is the acceleration of chemical transformations with a substoichiometric amount of an organic compound which does not contain a metal atom. Organocatalysts have emerged as powerful tools for organic transformations. Organocatalysts have several important advantages, since they are usually robust, inexpensive, readily available and non toxic. In our study, we have contributed the applications of new neutral pyrrolidine based chiral organocatalysts in the synthesis of a various valuable chiral and non-chiral products with several advantages from an economical and environmental...
