  • Tandem synthesis of 4-aminoxanthones is controlled by a water-assisted tautomerization: a general straightforward reaction
    作者:Ana Bornadiego、Jesús Díaz、Carlos F. Marcos
    DOI:10.1039/c8ob02527d
    日期:——
    synthetically challenging. Here, we report the synthesis of both aminodihydroxanthones and fully aromatized aminoxanthones by an easy to perform, one-step multicomponent reaction of isocyanides, 3-carbonylchromones and dienophiles. The mechanism of the reaction involves a sequence of a [4 + 1] cycloaddition, iminolactone-aminofuran tautomerization, [4 + 2] cycloaddition, oxygen ring opening and aromatization
    氧杂蒽酮是一组迄今为止在合成方面具有挑战性的有治疗前景的化合物。在这里,我们报告了异氰酸酯,3-羰基色酮和亲二体的易于执行的一步式多组分反应,合成了基二黄嘌呤和完全芳构化的黄嘌呤。该反应的机理包括[4 + 1]环加成,亚基内-呋喃互变异构,[4 + 2]环加成,环打开和芳构化的序列。值得注意的是,DFT量子化学计算显示亚基内-呋喃互变异构化需要分子的协助,与直觉相反,这是决定速率的步骤。相反,[4 +1]和[4 + 2]环加成都具有相对较低的计算能垒,无论起始原料上的取代基如何。因此,我们建立了直接和广泛合成的各种取代的氧杂蒽。这种高度趋同的过程也已用于合成生物学上重要的色酚吩并吡啶和与乙二酸有关的x吨二聚体。

    Reactions of 3-methoxalyl-, 3-polyfluoroacyl- and 3-aroylchromones with dimethyl 1,3-acetonedicarboxylate and 1,3-diphenylacetone in the presence of DBU proceed at the C-2 atom of the chromone system with pyrone ring-opening and subsequent formal [3 + 3] cyclocondensation to functionalized 2-hydroxybenzophenones, 6H-benzo[c]chromenes and benzo[c]coumarins, depending on the substituent at the 3-position. An NMR study and X-ray crystallographic analysis are reported. The compounds synthesized can be considered as promising scaffolds for the design of the novel UV-A/B and UV-B filters.

    The reaction of 5-amino-1H-imidazoles with 3-methoxalylchromone provided a set of imidazo[4,5-b]pyridines (1-des­azapurines) bearing the CO2Me substituent at the α-position of the pyridine core. The corresponding acids were synthesized by subsequent hydrolysis of the ester function. Being typical purine isos­teres, 1-desazapurines are considered to be potent pharmacophores, and are widely used in drug design and medicinal chemistry.

  • Regioselective Tandem [4 + 1]–[4 + 2] Synthesis of Amino-Substituted Dihydroxanthones and Xanthones
    作者:Ana Bornadiego、Jesús Díaz、Carlos F. Marcos
    DOI:10.1021/acs.joc.5b00658
    日期:2015.6.19
    A highly convergent and operationally simple approach to mycotoxin-related 4-amino-substituted 1-hydroxy-dihydroxanthones is described. The target compounds are obtained in one pot by the multicomponent reaction of 3-carbonylchromones, isocyanides, and nonsymmetric dienophiles. The reaction, which involves a tandem [4 + 1]-[4 + 2] cydoaddition, efficiently affords a variety of both monomeric and dimeric polysubstituted dihydroxanthones structurally similar to bioactive ergochromes. Further aromatization to the corresponding xanthones is readily achieved by treatment with DBU under microwave irradiation.
