HUDROXYCHALKONES AND THEIR ANALOGUES. SYNTHESIS WITH THE USE OF THE WITTIG REACTION

Synthesis of new hydroxychalkones and their analogs has been made on the basis of aromatic and heterocyclic aldehydes with phosphonium salts. The method of Wittig reaction in the presence of triethylamine has been worked out. The compounds obtained can show physiological activity and valuable pharmacological activity. They are also interesting in the context of use of derivatives of hydroxychalkones as compounds for synthesis of flavon type substances.
