    K2CO3-Catalyzed Synthesis of Chromones and 4-Quinolones through the Cleavage of Aromatic C–O Bonds
    摘要:
    Phenol-derived electrophiles are favorable substrates because phenols are naturally abundant or can be readily prepared from other aromatic compounds. However, the cleavage of aromatic C-O bonds Is a great challenge because of their high energy. K2CO3-catalyzed intramolecular cyclization of 1-(2-alkoxyphenyl)-3-akylpropane-1,3-dlone and 3-(alkylimino)-1-(2-methoxyphenyl)-2-methylpropan-1-one derivatives via the selective cleavage of aromatic C-O bonds Is reported. The corresponding chromone and 4-quinolone derivatives were obtained in reasonable yields.

    Ynones are privileged building blocks in various organic syntheses of heterocyclic derivatives due to their multifunctional nature, and flavones are an important class of natural products with a wide range of biological activities. We describe the catalytic double decarboxylative alkynylation of arylpropiolic acids with α‐keto acids. With Ag(I)/persulfate as the catalysis system, the valuable ynones
    壬烷由于其多功能性而成为杂环衍生物的各种有机合成中的重要组成部分,而黄酮是具有广泛生物活性的重要一类天然产物。我们描述了芳基丙酸与α-酮酸的催化双脱羧炔基化反应。以Ag(I)/过硫酸盐为催化体系,可以容易地获得带有各种取代基的有价值的炔酮。邻位羟基取代基的引入α-酮酸的位点使该策略进一步适用于通过异环戊烷以类似的银催化体系以中等到良好的收率构建黄酮衍生物。反应在相对温和的反应条件下进行,并能耐受多种官能团。对照实验表明,两个反应均经历自由基过程。

    A triazole bridged flavonoid dimer compound library was efficiently constructed via the cycloaddition reaction of a series of flavonoid-containing azides (Az 1-15) and alkynes (Ac 1-17). These triazole bridged flavonoid dimers and their precursor alkyne- and azide-continaing flavonoids were screened for their ability to modulate multidrug resistance (MDR) in P-gp-overexpressed cell line (LCC6MDR), MRPl-overexpressed cell line (2008/MRPl) and BCRP-overexpressed cell line (HEK293/R2 and MCF7-MX100). Generally, they displayed very promising MDR reversal activity against P-gp-, MRPl- and BCRP-mediated drug resistance. Moreover, they showed different levels of selectivity for various transporters. Overall, they can be divided into mono-selective, dual-selective and multi-selective modulators for the P-gp, MRPl and BCRP transporters. The EC50 values for reversing paclitaxel resistance (141 - 340 nM) of LCC6MDR cells, DOX (78 - 590 nM) and vincristine (82 - 550 nM) resistance of 2008/MRPl cells and topotecan resistance (0.9 - 135 nM) of HEK293/R2 and MCF7-MX100 cells were at nanomolar range. Importantly, a number of compounds displayed EC50 at or below 10 nM in BCRP-overexpressed cell lines, indicating that these bivalent triazoles more selectively inhibit BCRP transporter than the P-gp and MRPl transporters. Most of the dimers are notably safe MDR chemosensitizers as indicated by their high therapeutic index values.
    通过对一系列含有三唑基的黄酮类化合物(Az 1-15)和炔烃(Ac 1-17)进行环加成反应,高效构建了一个三唑桥联的黄酮二聚体化合物库。对这些三唑桥联的黄酮二聚体及其前体炔烃和三唑基的黄酮类化合物进行了筛选,以评估它们对P-gp过表达细胞系(LCC6MDR)、MRP1过表达细胞系(2008/MRP1)和BCRP过表达细胞系(HEK293/R2和MCF7-MX100)调节多药耐药性(MDR)的能力。总体而言,它们显示出对P-gp、MRP1和BCRP介导的药物耐药性具有非常有前景的MDR逆转活性。此外,它们对各种转运蛋白显示出不同程度的选择性。总体而言,它们可以分为对P-gp、MRP1和BCRP转运蛋白具有单选择性、双选择性和多选择性调节剂。逆转LCC6MDR细胞对紫杉醇耐药性(141-340 nM)、2008/MRP1细胞对阿霉素(78-590 nM)和长春碱(82-550 nM)耐药性以及HEK293/R2和MCF7-MX100细胞对托泊替康耐药性(0.9-135 nM)的EC50值在纳摩尔范围内。重要的是,许多化合物在BCRP过表达的细胞系中显示出EC50在或低于10 nM,表明这些双价三唑更具选择性地抑制BCRP转运蛋白而不是P-gp和MRP1转运蛋白。大多数二聚体根据其高治疗指数值显示出明显安全的MDR化疗敏感化剂特性。

    A domino reaction between 2‐hydroxy‐/2‐aminobenzaldehydes and α‐haloketones gives chromen‐4‐ones and quinolin‐4‐ones in good to excellent yields. This method represents a new extension of the Allan–Robinson and Friedländer reactions, and uses N‐heterocyclic‐carbene catalysis. This approach has the advantages of operational simplicity, ambient reaction conditions, and no by‐product formation.
