SYNTHESIS OF SOME SUBSTITUTED 9-ARYL XANTHENE DERIVATIVES

Abstract

Xanthene derivatives are very important heterocyclic compounds and have been widely used as<br><br>dyes fluorescent materials for visualization of biomolecules and laser technologies due to their<br><br>useful spectroscopic properties. [1] This compounds have also been investigated for agricultural<br><br>bactericidal activity, [2] photodynamic therapy, [3] anti-inflammatory effects, [4] antiviral activity,<br><br>[5] and for antagonism of the paralyzing action of zoxazolamine.[6] Because of the remarkable<br><br>properties, their synthesis has been considered by researchers.<br><br>Due to the widespread use of xanthene derivatives, various methods for their synthesis have been<br><br>reported. In this article we have reported synthesis of new and the most commonly used of xanthene<br><br>derivatives. For this purpose, the xanthydrol was reacted with different derivatives of 2-naphthol in<br><br>acidic conditions.
