Abstract

Surender Kumar and Dinesh Sharma

A simple and very efficient method for the oxidative cyclisation of 2'-hydroxychalcones with sodium tellurite in dimethylsulphoxide has been developed which could provide a simple route for the synthesis of flavones and also the required compound obtained as the sole product in a very high yield.
