FIELD: organic chemistry, steroids. SUBSTANCE: invention relates to inhibitors of steroid 5$$$-reductase of the following formula (I): $$$ where Y - oxygen or sulfur; R - group: $$$ where $$$ - hydrogen or $$$-alkyl; $$$ where each of $$$ and $$$ means independently hydrogen or $$$-alkyl; $$$ where $$$ - hydrogen or $$$-alkyl, and W - group: $$$ where $$$ - $$$-alkyl, $$$-cycloalkyl, $$$-cycloalkylalkyl, phenyl or benzyl group; or $$$ where $$$ - $$$-alkyl or $$$-cycloalkyl; or $$$ where $$$ and $$$ as indicated above; $$$ where each of $$$ and $$$ means independently hydrogen or $$$-alkyl, or both together with nitrogen atom with that they bound form pentaatom or hexaatom saturated heteromonocyclic ring involving at least one additional heteroatom taken from oxygen and nitrogen, and n = 2-4; $$$ - hydrogen, $$$-alkyl, $$$-cycloalkyl, $$$-cycloalkylalkyl or aryl group; each of $$$ and $$$ is taken independently from group consisting of hydrogen, $$$-alkyl, $$$-cycloalkyl, $$$-cycloalkylalkyl; or $$$ and $$$ together with nitrogen atom with that they bound form pentaatom or hexaatom saturated heteromonocyclic ring involving at least one additional heteroatom taken from oxygen and nitrogen; symbol $$$ means single or double bond at condition that in the case of double bond then hydrogen at 5$$$-position is absent, and its pharmaceutically acceptable salts. The synthesized compounds can be used in medicine. EFFECT: improved method of synthesis. 6 cl
