NOVEL BICYCLIC DIOXANES, PRODUCTION AND USE THEREOF AS AROMATIC COMPOUNDS Russian patent published in 2015 - IPC C07D319/08 C11D3/50 A61K8/33 

FIELD: chemistry.

SUBSTANCE: invention relates to novel compounds of formula (I), where: R³ and R⁴ are independently a hydrogen atom, a C₁-C₆ alkyl group or C₂-C₆ alkenyl group, R⁵ is a C₁-C₆ alkyl group, specifically methyl, ethyl, isobutyl, tert-butyl, n.-pentyl, C₂-C₆ alkenyl group or (CH₂)_0-2-aryl group, R⁶ is a C₁-C₆ alkyl group, C₂-C₆ alkenyl group, (CH₂)_0-2-aryl group or C₅-C₆ cycloalkyl or cycloalkenyl group, and R⁷ is a hydrogen atom, C₁-C₆ alkyl group or C₂-C₆ alkenyl group; or R³, R⁴ and R⁵ are as defined above, and R⁶ and R⁷ together with a carbon atom with which they are bonded form a C₅-C₆ cycloalkyl or cycloalkenyl group, as well as to an aromatic composition based on the compound of formula I, where R³, R⁴, R⁶ and R⁷ assume values given above, and R⁵ is a C₁-C₆ alkyl group.

EFFECT: obtaining novel compounds.
