METHOD OF PRODUCING 3-METHYL-6-(PROP-1-EN-2-YL)CYCLOHEX-3-ENE-1,2-DIOL Russian patent published in 2011 - IPC A61K31/15 A61P25/08 

FIELD: chemistry.

SUBSTANCE: invention relates to synthesis of organic compounds, specifically to selection and preparation of novel reaction media-solvents for converting organic compounds and methods of carrying out organic reactions, particularly production of 3-methyl-6-(prop-1-en-2-yl)cyclohex-3-ene-1,2-diol, which is obtained in a verbenol epoxide isomerisation reaction, carried out in a supercritical complex solvent at temperature not higher than 473 K and pressure not higher than 170 atm. The supercritical solvent used is a mixture of carbon dioxide CO₂ and aliphatic alcohols, with or without addition of water.

EFFECT: high rate and efficiency of the chemical process, independence of selectivity of the end product from initial concentration and rate of feeding reagents.
