    Synthesis, Antifungal Activity, and Structure−Activity Relationships of Coruscanone A Analogues
    摘要:
    Coruscanone A, a plant-derived cyclopentenedione derivative, showed potent in vitro antifungal activity against Candida albicans and Cryptococcus neoformans comparable to amphotericin B and fluconazole. A series of analogues have been synthesized by modification of the cyclopentenedione ring, the enolic methoxy functionality, and the side chain styryl moiety of this natural product lead. A structurally close 1,4-benzoquinone analogue was also prepared. All the compounds were examined for their in vitro activity against major opportunistic fungal pathogens including C. albicans, C. neoformans, and Aspergillus fumigatus and fluconazole-resistant C. albicans strains, with several analogues demonstrating potent antifungal activity. Structure-activity relationship studies indicate that the 2-methoxymethylenecyclopent-4-ene-1,3-dione structural moiety is the pharmacophore responsible for the antifungal activity of this class of compounds while the side chain styryl-like moiety plays an important complementary role, presumably contributing to target binding.

    摘要:
    多氮杂杂环化合物显示出过多的生物学特性,在临床使用的药物中占很大比例。然而,imizado[1,2- a ]嘧啶环系统在药物应用方面需要更多关注。在此,我们报告了一个涉及醛缩合/溴化/Hantzsch 反应的序列,以构建一系列 2-alkenylimidazo[1,2- a] 用于探索其细胞毒性和抗菌特性的嘧啶。经过初步筛选,两种化合物对前列腺癌、乳腺癌和结肠癌均表现出良好的细胞毒性;在苯乙烯基部分连接的庞大或额外的苯基似乎是良好活性的必要条件。关于抗菌作用,一些化合物对多重耐药性肺炎克雷伯菌表现出相当大的抑制作用,肺炎克雷伯菌是当今最具威胁性的细菌之一。因此,该系列可能成为设计更多活性化合物的基础。 图形概要

  • Enantioselective Cyclizations of Silyloxyenynes Catalyzed by Cationic Metal Phosphine Complexes
    作者:Jean-François Brazeau、Suyan Zhang、Ignacio Colomer、Britton K. Corkey、F. Dean Toste

    discovery of complementary methods for enantioselective transition metal-catalyzed cyclization with silyloxyenynes has been accomplished using chiral phosphine ligands. Under palladium catalysis, 1,6-silyloxyenynes bearing a terminal alkyne led to the desired five-membered ring with high enantioselectivities (up to 91% ee). As for reactions under cationic gold catalysis, 1,6- and 1,5-silyloxyenynes

    An efficient chemoselective general procedure for the synthesis of γ‐substituted β,γ‐unsaturated α‐ketomethylthioesters from α,βunsaturated ketones has been achieved through an unprecedented PPh3⋅HBr‐DMSO mediated oxidative bromination and Kornblum oxidation sequence. The newly developed reagent system serves admirably for the synthesis of α‐bromoenals from enals. Furthermore, AuCl3‐catalyzed efficient

    Direct polarity inversion of conjugate acceptors provides a valuable entry to homoenolates. N‐heterocyclic carbene (NHC) catalyzed reactions, in which β‐unsubstituted conjugate acceptors undergo homoenolate formation and C−C bond formation twice, have been developed. Specifically, the all‐carbon (5+1) annulations give a range of mono‐ and bicyclic cyclohexanones (31 examples). In the first family of
    共轭受体的直接极性反转提供了一个有价值的进入均烯酸酯的途径。已经开发出了N-杂环卡宾(NHC)催化的反应,其中β-未取代的共轭受体经历了均烯酸酯形成和C-C键形成两次。具体而言,全碳(5 + 1)环空给出了一系列单环和双环环己酮(31个示例)。在第一个环族中,束缚在二乙烯基酮上的β-未取代的丙烯酸酯会进行环异构化,从而提供六氢和四氢化。在第二部分中,部分未束缚的底物经历分子间(5 + 1)环合反应,其中涉及二聚化,然后进行环异构化。尽管前者不可能实现对映选择性,但后者被证明是可行的,从而可以生产出高平的对映体纯度的环己酮(大多数> 95:5 er)和非对映选择性(> 20:1 dr)。还报道了衍生化和机理研究。

    The highly enantioselective hydrogenation of 3-aryl-2H-1,4-benzoxazines was achieved using the (cyclooctadiene)iridium chloride dimer/(S)-SegPhos/iodine [Ir(COD)Cl]2/(S)-SegPhos/I2} system as catalyst with up to 92% ee. The 3-styryl-2H-1,4-benzoxazine derivatives were also hydrogenated by the iridium catalyst and Pd/C in two consecutive steps whereby 93–95% ee values were obtained.
