  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.

  亲核加氧剂的性质是无酸金催化末端和内部炔烃转化为1,2-二羰基的关键。

  摘要：

  2,3-二氯吡啶N-氧化物，一种新型的氧转移试剂，可在不存在任何酸添加剂且在温和条件下，将金（I）催化的炔烃氧化为1,2-二羰基的电导，以提供目标物种，包括那些由高度酸敏感性基团衍生的物种。所开发的策略可用于多种炔烃底物，例如末端和内部炔烃，乙酰胺，炔基醚/硫醚，甚至未取代的乙炔（40例；产率高达99％）。通过一锅杂环化成功地将氧化整合到捕获反应性二羰基化合物中，并整合到六元氮杂杂环的合成中。这种无酸合成路线也成功地用于天然1,2-二酮的全合成。

  2,3-Dichloropyridine N-oxide, a novel oxygen transfer reagent, allows the conductance of the gold(I)-catalyzed oxidation of alkynes to 1,2-dicarbonyls in the absence of any acid additives and under mild conditions to furnish the target species, including those derivatized by highly acid-sensitive groups. The developed strategy is effective for a wide range of alkyne substrates such as terminal- and
