FIELD: organic chemistry, medicine, pharmacy.
SUBSTANCE: invention relates to 2-hetaryl-substituted derivatives of 1,2-tropolones of the general formula (Ia): 
wherein R1 and R2 mean (C1-C6)-alkyl; R3 means hydrogen atom, (C1-C6)-alkyl, nitro-group; Het means six-membered nitrogen heterocycle condensed with one or two benzyl rings that can be substituted with substitutes chosen from group comprising halogen atom, nitro-group, (C1-C6)-alkyl, oxy-(C1-C6)-alkyl, secondary amino-group chosen from anilino-, substituted anilino-, hydroxyethylamino-group, or tertiary amino-group chosen from morpholino-, piperidino-, piperazino-group, 1H-1-imidazolyl. Also, invention relates to a method for synthesis of 2-hetaryl-substituted derivatives of 1,3-tropolone. Method involves condensation of benzoquinones-1,2 with 2-methylheterocycles at heating in the presence of acetic acid taken in the amount providing its role as both a catalyst and a solvent. Also, invention relates to a pharmaceutical composition with antibacterial effect based on 2-hetaryl-substituted derivatives of 1,3-tropolone.
EFFECT: improved method of synthesis, valuable medicinal properties of compounds and pharmaceutical composition.
