    Preparation of chiral building blocks for the enantioselective total synthesis of ent-kauranoids by the pig liver esterase-catalyzed asymmetric hydrolysis of a dialkyl malonate-type prochiral diester
    摘要:
    The preparation of chiral building blocks, suitable for use in the enantioselective total synthesis of kauranoids and ent-kauranoids, is reported herein. The pig liver esterase-catalyzed asymmetric hydrolysis of dimethyl 3,3-dimethyl-2-methylenecyclohexane-1,2-dicarboxylate, a malonate-type prochiral diester, afforded the corresponding half-ester in 96% yield and with 99% enantiomeric excess. The absolute configuration of the half-ester was determined by X-ray crystallographic analysis of its derivative and its enantiodivergent transformations are also described herein.

  • Synthetic studies on the icetexones: enantioselective formal syntheses of icetexone and epi-icetexone
    作者:Felipe de Jesus Cortez、David Lapointe、Amy M. Hamlin、Eric M. Simmons、Richmond Sarpong
    DOI:10.1016/j.tet.2013.04.049
    日期:2013.7
    This approach was ultimately unsuccessful and led only to ring cleaved products. In the second approach, an alkynyl indene substrate bearing a cyano substituent was utilized, which was effective in providing a functional handle to access the icetexone subclass of diterpenoids. A key epoxide opening/diazene rearrangement sequence was utilized to complete a formal synthesis of icetexone and epi-icetexone
    已经探索了两种合成icetexane 二萜类icetexone 和epi- icetexone 的策略,它们依赖于Ga(III) 催化的炔基底物环异构化以产生稠合的[6-7-6] 三环。在第一种方法中,使用带有宝石的三轮车-二甲基为探索靠近羟基导向基团的甲基之一的 C-H 官能化铺平了道路。这种方法最终不成功并且仅导致环裂解产物。在第二种方法中,使用带有基取代基的炔基底物,它有效地提供了访问二萜类icetexone亚类的功能性手柄。一个关键的环氧化物开环/二氮烯重排序列被用来完成icetexone和epi- icetexone的正式合成,详细讨论。此外,使用 Rh 催化的共轭加成反应制备了对映体富集形式的含基底物,这为这些天然产物的对映选择性合成提供了一条途径。
  • Ga(III)-Catalyzed Cycloisomerization Strategy for the Synthesis of Icetexane Diterpenoids:  Total Synthesis of (±)-Salviasperanol
    作者:Eric M. Simmons、Richmond Sarpong
    DOI:10.1021/ol061037c
    日期:2006.6.1
    [reaction: see text] A general approach to the tricyclic core of the icetexane natural products via the cycloisomerization of alkynyl indenes using GaCl(3) is presented. This strategy provides an efficient synthesis of the natural product salviasperanol and sets the stage for access to other members of this family of diterpenoids.
    [反应:见正文]提出了一种通过使用GaCl(3)炔基基的环异构化方法来制备icetexane天然产物三环核心的一般方法。该策略提供了天然产物丹参戊醇的有效合成,并为获得该双萜类家族的其他成员奠定了基础。
