    摘要:
    我们报道了[Ru(对-cymene)(l-脯氨酸)Cl]([Ru1])催化的1,4,2-二恶唑-5-酮环化反应形成二氢喹啉-2-酮,具有优异的产率和极好的区域选择性通过正式的分子内芳烃C(sp 2)–H酰胺化。2-和4-取代的芳基二恶唑酮的反应首先通过在芳烃位点上的亲电酰胺化的螺内酰胺化进行,该芳烃位点对取代基是对位的或邻位的。Hammett相关性研究表明,螺内酰胺化可能是由于对苯丙氨酸的亲电子亚硝基化合物攻击而发生的,其特征是-0.73的负ρ值。

    ABSTRACT A thorough study on radical-induced cyclopropyl ring fragmentation with encompassed olefinic and cyclopropane environment has been performed. Interestingly, the fragmentation has occasioned onto a stereoselective synthesis of 3-allyl trans-2,3-dihydrobenzofurans with impressive yields. The trans-dihydrobenzofurans are present as central core in many molecules of medicinal interest and the

    We have developed a divergent strategy for the synthesis of five- and six-membered lactams via either an amidation of sp3 C-H bonds or electrophilic substitution of arenes via Ir-nitrene intermediates. With the employment of a readily available iridium catalyst in dichloromethane or hexafluoro-2-propanol, a wide range of lactams were synthesized in good to excellent yields with high selectivity.
    我们已经开发了一种通过sp3 CH键的酰胺化或Ir-nitrene中间体亲电取代芳烃来合成五元和六元内酰胺的策略。通过在二氯甲烷或六氟-2-丙醇中使用易于获得的铱催化剂,以高至优异的产率和高选择性合成了多种内酰胺。

    ortho-hydroxylcinnamate ester derivatives by using diaryliodonium(III) salts has been developed. With this method, 4-arylcoumarins were easily prepared in good to excellent yields under base-free conditions. Additionally, this protocol provided an efficient alternative for the preparation of related 4-arylated coumarin compounds which are useful in the access to 5-lipoxygenase inhibitors.

  • Prenylcoumarin with Rev-export inhibitory activity from Cnidii Monnieris Fructus
    作者:Satoru Tamura、Toshiaki Fujitani、Masafumi Kaneko、Nobutoshi Murakami
    DOI:10.1016/j.bmcl.2010.04.081
    日期:2010.6
    By use of the fission yeast expressing the model fusion protein comprised of GST, SV40 T antigen NLS, GFP, and Rev-NES in the bioassay, the prenylcoumarin osthol (1) was disclosed as the new Rev-export inhibitor from the MeOH extract of Cnidii Monnieris Fructus. Furthermore, 1 was also found to inhibit export the genuine Rev in HeLa cells by indirect fluorescent antibody technique. By the competitive experiment using the biotinylated probe 3, osthol (1) was revealed to inhibit nuclear export of Rev through a NES non-antagonistic mode. Structure-activity relationship analysis of several analogs of 1 clarified that both prenyl side chain and double bond adjacent to the lactone carbonyl residue play an important role in the Rev-export inhibitory potency of 1.
