  Synthesis of 5α-Androstane-3α,16α,17β-triol from 3β-hydroxy-5-androsten-17-one

  摘要：

  5 alpha-Androstane-3 alpha, 16 alpha, 17 beta-triol was synthesized from 3 beta-hydroxy-5-androsten-17-one. The procedure involved catalytic hydrogenation of 3 beta-hydroxy-5-androsten-17-one to 3 beta-hydroxy-5 alpha-androstan-17-one. This was followed by conversion of the 3 beta-hydroxy group to 3 alpha-benzoyloxy group by the Mitsunobu reaction. Further treatment with isopropenyl acetate yielded 5 alpha-androsten-16-ene-3 alpha, 17-diol 3-benzoate 17-acetate. This was then converted to 3 alpha, 17-dihydroxy-5 alpha-androstan-16-one 3-benzoate 17-acetate via the unstable epoxide intermediate after treatment with m-cloroperoxybenzoic acid. LiA1H4 reduction of this compound formed 5 alpha-androstane-3 alpha, 16 alpha, 17 beta-triol. 1H and 13C NMR of various steroids are presented to confirm the structure of this compound.

• Epimerization of Tertiary Carbon Centers via Reversible Radical Cleavage of Unactivated C(sp³)–H Bonds

  cleavage of C(sp3)-H bonds can enable racemization or epimerization, offering a valuable tool to edit the stereochemistry of organic compounds. While epimerization reactions operating via cleavage of acidic C(sp3)-H bonds, such as the Cα-H of carbonyl compounds, have been widely used in organic synthesis and enzyme-catalyzed biosynthesis, epimerization of tertiary carbons bearing a nonacidic C(sp3)-H bond

  C(sp3)-H 键的可逆断裂可以实现外消旋化或差向异构化，为编辑有机化合物的立体化学提供了宝贵的工具。虽然通过裂解酸性 C(sp3)-H 键（例如羰基化合物的 Cα-H）进行的差向异构化反应已广泛用于有机合成和酶催化生物合成，但带有非酸性 C(sp3) 的叔碳的差向异构化-H 键更具挑战性，可用的实用方法很少。在这里，我们报告了第一个合成有用的协议，用于在温和条件下通过未活化的 C(sp3)-H 键与高价碘试剂苯并恶唑叠氮化物和 H2O 的可逆自由基裂解来进行叔碳差向异构化。这些反应对各种环烷烃的未活化 3° CH 键表现出优异的反应性和选择性，并为编辑传统方法难以处理的碳支架的立体化学构型提供了强大的策略。机理研究表明，N3• 作为催化氢原子穿梭的独特能力对于以高效率和选择性可逆地破坏和重组 3° CH 键至关重要。
