Исходным соединением в данной схеме является коммерчески доступный тестостерон пропионат, который был превращен в 3β-ацетокси-17b-пропи­ онилоксиандрост-5-ен. Присоединение бромноватистой кислоты по 5(6)-двойной связи этого соединения привело к 3-ацетату 17-пропионату 5-бром-5a-андростан-3β,6β,17β-триола. Окисление последнего тетраацетатом свинца дает 3-ацетат 17-пропионат 5-бром-6b,19-оксидо-5a-андростан-3β,17β-диола, из которого при селективном метанолизе 3b-ацетоксигруппы получен 17-пропионат 5-бром-6b,19-оксидо-5a-андростан-3β,17β-диола. В результате окисления 3b-гидроксигруппы в данном соединении хромовой кислотой и последующего восстановления образовавшегося 3-кетона цинковой пылью в метилэтилкетоне получен 19-гидрокситестостерон 17-пропионат. Окисление получен­ного 19-гидроксистероида хромовой кислотой с последующим декарбоксилированием 19-карбоновой кислоты при нагревании в смеси пиридина с бензолом привело к образованию целевого 19-нортестостерон пропионата. </p></abstract><trans-abstract xml:lang="en"><p>Synthesis of androgen 19-nortestosterones via new synthetic scheme has been achieved. The synthesis commenced with commercially available testosterone propionate which was transformed to 3β-acetoxy-17β-propyonyloxy-androst-5-en. Hypobromous acid was added to the 5(6)-double bond of the latter compound leading to 3-acetate 17-propionate 5-bromo-5αandrostane-3β,6β,17β-triol that was oxidized by lead tetraacetate giving the 3-acetate 17-propionate 5-bromo-6β,19-oxido5α-androstan-3β,17β-diol. Selective hydrolysis of the acetate group of the latter provided 17-propionate 5-bromo-6β,19-oxido5α-androstan-3β,17β-diol. Oxidation of the 3β-hydroxy group of the obtained compound by chromic acid followed by reduction of the resulting 3-keto group by zinc dust in methylethylketone gave 19-hydroxytestosterone-17-propionate. Oxidation of the resulting 19-hydroxysteroid by chromic acid and subsequent decarboxylation of 19-carboxylic acid by its heating in a mixture of pyridine and benzene led to the target 19-nortestosterone propionate.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>19-нортестостерон пропионат</kwd><kwd>тестостерон пропионат</kwd><kwd>стероиды</kwd><kwd>андрогены</kwd><kwd>химический синтез</kwd></kwd-group><kwd-group xml:lang="en"><kwd>19-nortestosterone propionate</kwd><kwd>testosterone propionate</kwd><kwd>steroids</kwd><kwd>androgens</kwd><kwd>chemical synthesis</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Zeelen, F.
