A new synthesis of flavonoids via Heck reaction

A new efficient method to obtain the basic skeleton of flavonoids is described herein, The key step involves the use of the Heck reaction for the synthesis of the intermediate chalcone, Results, The synthetic strategy we propose, as shown in Scheme 1, consists of the use of the Heck coupling reaction between an α,β-unsaturated ketone, such as

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 [1], anti-inflammatory [2], anti-oxidant [3] and anti-cancer [4], In some basic methods of synthesis of flavones aldehydes

Species-specific differences in synthesis of flavonoids

Flavonoids and monolignols are synthesized by two different routes: if synthesis of quercetin and other flavonoids is enhanced under blue light it may lead to a decrease in the monolignols needed in lignin biosynthesis, This may cause decreased growth through affecting chalcone synthase activity and auxin transport,

Flavonoids are low molecular weight secondary metabolites that are produced by plants, and generally are described as non- essential for plant survival, unlike primary metabolites, Secondary products are biologically active in many ways, and over 10,000 structural variants of flavonoids have been reported Williams and Grayer, 2004; Ferrer et al,, 2008; their synthesis appears to be

Chemistry and Biological Activities of Flavonoids: An Overview

Chemical synthesis of flavonoids requires extreme reaction conditions and toxic chemicals , Because of the rapid development in molecular biology tools and the flooding of genome information from a variety of organisms, combinatorial biosynthesis offers an advantage for production of rare and expensive natural products, It can be used in both simple and complex transformations without the
