FIELD: chemistry.
SUBSTANCE: invention relates to field of organic chemistry, in particular to method of obtaining 3,3-di(methoxycarbonyl)-1,5-dithiacycloalkanes of general formula (I): X=(CH2)n, where n=1, 2, consisting in the following: formaldehyde (37%) is subjected to interaction with hydrogen sulphide or 1,2-ethanedithiol and dimethyl ether of malonic acid in presence of catalyst FeCl3 with molar ratio CH2O : hydrogen sulphide : dimethyl ether of malonic acid: FeCl3=3:2:1:(0.03-0.07) or CH2O : 1,2-ethanedithiol : dimethyl ether of malonic acid: FeCl3=2:1:1:(0.03-0.07), at room temperature (~20°C) and atmospheric pressure for 6-9 h in mixture of solvents chloroform-ethanol (volume 1:1).
EFFECT: elaborated is method of obtaining 3,3-di(methoxycarbonyl)1,5-dithiacycloalkanes, which can be widely applied as biologically active substances.
