    Ultrasound-assisted synthesis of symmetrical biaryls by palladium-catalyzed detelluration of 1,2-diarylditellanes
    摘要:
    An ultrasound-assisted synthesis of functionalized symmetrical biaryls with electron-withdrawing or electron-donating substituents is described and illustrated by the palladium-catalyzed detelluration of 1,2-diarylditellanes. This procedure offers easy access to symmetrical biaryls in short reaction time and the products are achieved in good to excellent yields. (c) 2009 Published by Elsevier Ltd.

  • Sunlight Oxidation of Alkyl Aryl Tellurides to the Corresponding Carbonyl Compounds: A New Carbonyl Precursor
    作者:Akihiko Ouchi、Takeshi Hyugano、Chuanxiang Liu
    DOI:10.1021/ol901943f
    日期:2009.11.5
    Alkyl aryl tellurides were efficiently transformed to the corresponding carbonyl compounds by photo-oxidation with sunlight without affecting various functional groups in the alkyl moiety. The tellurides can be used as a new carbonyl precursor, and the photolysis can be conducted without special equipment for light sources.
    通过在不影响烷基部分中各种官能团的情况下用阳光进行光氧化,将烷基芳基碲化物有效地转化为相应的羰基化合物。碲化物可以用作新的羰基前体,并且无需使用专门的光源设备即可进行光解。

    We have synthetized a novel series of β-hydroxy tellurides bearing the benzenesulfonamide group as potent inhibitors of carbonic anhydrase enzymes. In a one pot procedure, we discovered both the ring opening reaction of the three-membered ring and the cleavage of the sulfonamide protecting moiety at the same time. Moreover, the first X-ray co-crystallographic structure of a β-hydroxy telluride derivative
    我们已经合成了一系列新型的带有苯磺酰胺基团的β-羟基碲化物,它们是碳酸酐酶的有效抑制剂。在一个一锅法中,我们同时发现了三元环的开环反应和磺酰胺保护基团的裂解。此外,已经报道了β-羟基碲化物衍生物与hCA II的第一X射线共晶体结构。这些化合物对具有低纳摩尔常数抑制值的肿瘤相关hCA IX的有效作用使得有可能使用乳腺癌细胞系(MDA-MB-231)在体外评估其活性。化合物7e和7g在常氧条件下孵育48小时后,其对肿瘤细胞具有明显的毒性作用,在3μM的条件下杀死了50%以上的肿瘤细胞,但在低氧条件下,其功效却下降了,仅在30μM时达到了肿瘤细胞活力的50%。这些不同寻常的特征使它们成为有趣的先导化合物,不仅可以作为抗碳酸酐酶IX的抑制剂,而且可以作为抗肿瘤药,而且在不过度表达hCA IX的不同途径中也可以发挥作用。
