Synthesis of Flavones

Abstract

Medicinal properties of the plants are attributed due to presence of various flavonoids. Flavone is one class of flavonoids which attracted the attention of researchers worldwide. These ‘yellow’ colored compounds have 2-phenylchromen-4-one backbone structure. Flavones contribute to various medicinal properties like anti diabetic , anti-inflammatory , anti-oxidant and anti-cancer . In some basic methods of synthesis of flavones aldehydes react with hydroxyl aceto phenones under claisensmith condensation. In this review we have tried to summarize the various methods of synthesis of flavones.
