FIELD: organic chemistry. SUBSTANCE: invention relates to new propinyl-diaromatic compounds containing propinyl link of the general formula (I) $$$ where Ar means radical taken from radicals of the following formula: $$$ where $$$ - H, $$$ or $$$; X - radical of the formula $$$ or $$$ where $$$ and $$$ - H, lower alkyl of direct or branched chain or $$$, or together with $$$ and $$$ they form 5- or 6-membered cycle; $$$ - H or lower alkyl or $$$, $$$ = $$$; $$$ - H or lower alkyl or $$$; $$$ - H, lower alkyl or $$$ or $$$ where $$$ and $$$ - H or lower alkyl; $$$ - H or alkyl; $$$ - lower alkyl; $$$ - H, lower alkyl or radical $$$; $$$ - radical $$$. Radicals $$$ and $$$ taken together can form oxo-group (C=O), and their salts with alkaline or alkaline-earth metals or zinc. The latter can be used in pharmaceutical compositions for use in medicine or veterinary science or in cosmetic compositions. Invention relates to pharmaceutical and cosmetic compositions also. EFFECT: improved method of synthesis. 12 cl, 3 dwg, 4 tbl
