    Highly Efficient and Scalable Synthesis of Clionamine D
    摘要:
    Herein we describe an efficient and scalable synthesis of clionamine D (4), a special member with autophagy bioactivity and an unprecedented spirobislactone side chain in the novel aminosteroid clionamines. This synthesis features a quick access to alpha-methylene-gamma-lactone 8 and a Mn(OAc)(3)-mediated radical [3 + 2] reaction to assemble the unique spirobislactone unit. Clionamine D (4) can also serve as a key synthetic precursor to other clionamine members.

  • Gram-Scale Synthesis of Tomatidine, a Steroid Alkaloid with Antibiotic Properties Against Persistent Forms of <i>Staphylococcus aureus</i>
    作者:Chad Normandin、François Malouin、Eric Marsault
    DOI:10.1002/ejoc.202000051
    日期:2020.5.14
    The first synthesis of the Solanum alkaloid tomatidine was achieved in 24.9 % (longest linear sequence) through addition of a chiral organolithium fragment to a protected dinorcholanic lactone derived from commercially available diosgenin. This approach enabled the multigram synthesis with the goal to support further studies of its antibiotic properties against persistent forms of Staphylococcus aureus
    通过将手性有机锂片段加到衍生自市售薯os皂苷元的受保护的二降胆酸内酯中,茄类生物碱番茄碱的首次合成以24.9%(最长的线性序列)实现。这种方法使多谱图合成成为可能,其目标是支持其针对持久性金黄色葡萄球菌的抗生素特性的进一步研究。
  • Development of Biomimetic Synthesis of Propindilactone G <sup>†</sup>

    of concise biomimetic synthesis of propindilactone G from a known steroid lactone. The key C19‐OH intermediate was synthesized via Breslow and Suárez radical remote C—H functionalizations. Wagner‐Meerwein rearrangement was subsequently utilized for the expansion of the B ring. To invert the configuration of the C10 tertiary alcohol, an intramolecular peroxide cyclization catalyzed by BF3·Et2O was devised
