  Novel Macrocyclic Amidinoureas: Potent Non-Azole Antifungals Active against Wild-Type and Resistant Candida Species

  摘要：

  Novel macrocyclic amidinourea derivatives 11, 18, and 25 were synthesized and evaluated as antifungal agents against wild-type and fluconazole resistant Candida species. Macrocyclic compounds 11 and 18 were synthesized through a convergent approach using as a key step a ring-closing metathesis macrocyclization reaction, whereas compounds 25 were obtained by our previously reported synthetic pathway. All the macrocyclic amidinoureas showed antifungal activity toward different Candida species higher or comparable to fluconazole and resulted highly active against fluconazole resistant Candida strains showing in many cases minimum inhibitory concentration values lower than voriconazole.

  铜催化Cope型非活化烯烃向环硝基的加氢胺化：范围，机理和对映选择性过程的发展。

  摘要：

  环状硝酮的催化合成，对于合成化学和相关领域而言是重要的功能分子类型，但仍未得到开发。在本文中，我们报告了铜与悬垂的非活化烯烃进行肟的铜催化的Cope型加氢胺化反应，这使得在温和条件下易于获得一系列五元和六元环状硝酮。在这项研究中，第一次将杂环系肟用于Cope型加氢胺化反应。碳连接的γ，δ-乙烯基肟实现了高对映选择性，从而提供了对映体富集的五元环硝酮。初步机理研究的结果表明，在大温度范围内，单核催化物种和统一的催化途径。

  catalyst give access to indoles, 1,4-dihydroquinolines, and 1,2-dihydroisoquinolines, respectively. This sequential protocol also allows the synthesis of dihydrobenzoazepines, although the ring-closing metathesis (RCM) step is complicated by the alkene isomerization processes. From certain substrates, the direct annulation is observed in the titanium-mediated step, which is likely to occur through an

  An asymmetric unactivated alkene/CH bond difunctionalization reaction for the concomitant construction of CCF3 and CO bonds was realized by using a Cu/Brønsted acid cooperative catalytic system, thus providing facile access to valuable chiral CF3‐containing N,O‐aminals with excellent regio‐, chemo‐, and enantioselectivity.

Herein we report the copper-catalyzed Cope-type hydroamination of oximes with pendant nonactivated olefins, which enables facile access to a series of five- and six-membered cyclic nitrones under mild conditions. In this study, heterocycle-tethered oximes were employed in the Cope-type hydroamination reaction for the first time. High enantioselectivity was achieved for carbon-tethered
