Mozgunova E.M., Mukovoz P.P., Kozminykh V.O. SYNTHESIS AND PECULIARITIES OF STRUCTURE OF SODIUM ENOLATES AND ESTERS OF 2, 4, 6, 7, 9-PENTAOXODECANOIC ACIDS Sodium enolates and corresponding ethyl and methyl esters of 2, 6, 7-trihydroxy-4,9-dioxo-2,5,7-decatrienoic acids are got with ester condensation of Klizen. The features of the structure of synthesized polyketids with joined α-, β-dioxolinks are discussed in this article.Key words: ester condensation of Klizen, polyketids, α-, β-dioxolinks, ethers of pentaoxodecanoic acid.
