Abstract

There are a number of methods available for the synthesis of flavones and their derivatives. 5 The cyclodehydration of 1-(o-hydroxyphenyl)-1, 3 diketones is one of the most commonly used methods for the synthesis of subtituted flavones. 6 The basic aproach of the synthesis of the 1, 3-diketones consists of acylation of o-hydroxyacetophenone using different acylating agent and experimental conditions. 7-9 In Baker-Venkataraman synthesis, the ...
