  Structure–activity relationships of SERMs optimized for uterine antagonism and ovarian safety

  摘要：

  Structure-activity relationship studies are described, which led to the discovery of novel selective estrogen receptor modulators (SERMs) for the potential treatment of uterine fibroids. The SAR studies focused on limiting brain exposure and were guided by computational properties. Compounds with limited impact on the HPO axis were selected using serum estrogen levels as a biomarker for ovarian stimulation. (c) 2007 Elsevier Ltd. All rights reserved.

• Electrochemical Synthesis of (Aza)indolines<i>via</i>Dehydrogenative [3+2] Annulation: Application to Total Synthesis of (±)-Hinckdentine A

  DOI：10.1002/cjoc.201800301

  日期：2018.10

  An electrochemical synthesis of functionalized (aza)indolines through dehydrogenative [3+2] annulation of arylamines with tethered alkenes has been developed. Previous reported syntheses through similar inter‐ and intramolecular annulation reactions required noble‐metal catalysts and are mostly limited to terminal alkenes or 1,3‐dienes. The electrosynthesis employs the easily available and inexpensive

  已经开发了通过芳胺与链状烯烃的脱氢[3 + 2]环合进行官能化（氮杂）二氢吲哚的电化学合成方法。先前报道的通过类似的分子间和分子内环化反应进行的合成需要贵金属催化剂，并且大多限于末端烯烃或1,3-二烯。电合成采用容易获得且便宜的二茂铁作为分子催化剂，并与二，三，甚至四取代的烯烃相容，以构建二氢吲哚以及更具挑战性的氮杂二氢吲哚。利用新开发的电合成作为关键步骤，已从市售材料中分12个步骤（最长的线性序列）完成了海洋生物碱（±）-扁桃碱A的全合成。
