    New α-alkynyl, α-CF3 amino esters have been prepared from electrophilic imines and used to produce 3-alkenyl-3,4-dehydroproline derivatives, ia enyne metathesis with the precatalyst [RuCCCPh2(Cl)(PCy3)(arene)]O3SCF3. These new conjugated fluorine-containing dienes are active substrates for the Diels–Alder reaction and lead to a new class of bicyclic amino esters.
    新型α-炔基和α-CF3基酯已从电亲核亚胺合成,并用于通过与前催化剂[RuCCCPh2(Cl)(PCy3)(arene)]O3S 的炔烯复分解反应生成3-烯基-3,4-脱氢脯酸衍生物。这些新的含共轭二烯是Diels–Alder反应的活性底物,并导致一种新的双环酯类别的形成。

    mifepristone (1) led to the discovery of novel mifepristone derivatives with improved selectivity profile. Addition of a methyl group at the C10 position of the steroid has a significant impact on progesterone receptor (PR) and androgen receptor (AR) activity. Within this series, OP-3633 (15) emerged as a glucocorticoid receptor (GR) antagonist with increased selectivity against PR and AR, improved
    米非司酮的基于结构的修饰(1)导致发现了具有改进选择性的新型米非司酮生物。在类固醇的C10位置添加甲基对孕酮受体(PR)和雄激素受体(AR)活性具有重要影响。在该系列中,OP-3633(15)成为糖皮质激素受体(GR)拮抗剂,与1相比具有更高的抗PR和AR选择性,改善的细胞色素P450抑制特性以及显着改善的药代动力学特性。此外,有15个证明对GR具有实质性抑制作用GR阳性HCC1806三阴性乳腺癌异种移植模型中的转录活性。总体而言,化合物15是有前途的GR拮抗剂候选物,可用于临床评估GR抑制在逆转或预防治疗耐药性方面的影响。
  • Scalable Synthesis of a Key Intermediate for the Production of Pleuromutilin-Based Antibiotics
    作者:Stephen K. Murphy、Mingshuo Zeng、Seth B. Herzon
    DOI:10.1021/acs.orglett.7b02476
    日期:2017.9.15
    An improved synthesis of an eneimide, which is a useful precursor to pleuromutilin-based antibiotics, is reported. This synthesis proceeds in six steps and 17% overall yield (27% based on recovery of a key hydrindenone intermediate) and requires two fewer chromatography steps and five fewer days of reaction time than the previously reported route. The use of expensive, acutely toxic, and precious metal
    据报道,烯酰亚胺的合成得到了改进,烯酰亚胺是基于截短侧耳素的抗生素的有用前体。该合成分六个步骤进行,总产率为 17%(基于关键的酮中间体的回收率为 27%),并且比之前报道的路线少了两个色谱步骤和五天的反应时间。昂贵的、剧毒的和贵属试剂或催化剂的使用已经被最小化。

    the resulting carbanion 2 reacted with trifluoroacetic anhydride to give the trifluoroacylated phosphonate 3. Without isolation, 3 was attacked by lithium acetylides and elimination of phosphate anion afforded trifluoromethylated (Z)-ynenyl sulfones (Z-4) in 57–76% yields, while treatment of 3 with acetylenic Grignard reagents gave trifluoromethylated (E)-ynenyl sulfones (E-4) in 45–54% yields. The configuration
