METHOD OF SYNTHESIS OF 4-ALKYLPYROCATECHINS Russian patent published in 1997 - IPC

Abstract RU 2084438 C1

FIELD: organic chemistry and technology. SUBSTANCE: product: compound of the general formula where: R - tert.-C₄H₉, tert.-C₅H₁₁, tert. -C₆H₁₃, tert.-C₈H₁₇, sec.-C₁₀H₂₁, tert.--C₁₀H₂₁-, cyclo-C₆H₁₁.. Pyrocatechin is alkylated with the corresponding alcohols in presence of catalyst. Alkylation is carried out without solvent using two-fold excess of alcohol and phosphoric acid. Method provides the synthesis of broad series of 4-alkylpyrocatechins. EFFECT: improved method of synthesis. 2 tbl
