Synthesis of o(m)-carborane-containing azomethines
摘要:
A method of preparative synthesis of o(m)-carborane-containing azomethines via the condensation of o(m)-carboranyl-C-methylene-4-formylbenzoates with aliphatic, cycloaliphatic, and aromatic amines was developed.
合成了两个系列,包括 20 种带有硫脲基连接的吡唑8和氨基-1,2,4-噻二唑10的新型苯磺酰胺,并作为人碳酸酐酶 (hCA) 抑制剂针对亚型 I 和 II 以及肿瘤相关亚型 IX 和十二.还针对亚型 hCA I、II 和 XII 进行了一些有效衍生物( 8a 、 8c 、 10a和10c )的分子模型研究。这两个有前景的系列化合物都是使用市售的甲基酮和磺胺作为起始原料合成的。有趣的是,本文还报道了一种使用3-氨基异恶唑和4-异硫氰酸苯磺酰胺作为反应物合成氨基-1,2,4-噻二唑10的新方法。所有新合成的化合物的活性特征表明,与硫脲基连接的吡唑8相比,氨基连接的 1,2,4-噻二唑10是胞质异构体 hCA I 更好的抑制剂。此外,hCA II 几乎被所有新合成的磺酰胺类药物强烈抑制,而与标准药物乙酰唑胺相比,所有化合物作为 hCA IX 和 XII 抑制剂的效果较差。然而,就选择性而言,化合物8e被发现是hCA

The E-isomers of α-chlorocinnamonitriles react with hydroxylamine to give a mixture of isomeric aminoisoxazoles, while the Z-isomers yield 3-aryl-2-chloroacrylamide oximes.
α-氯肉桂腈的E异构体与羟胺反应生成一 mixture of isomeric aminoisoxazoles,而Z异构体则产生3-芳基-2-氯丙烯酰胺肟。
Syntheses, structures and properties of magnetically active copper(II) compounds with 3-amino-5-(4-methylphenyl)isoxazole
Novel copper(II) coordination compounds with 3-amino-5-(4-methylphenyl)isoxazole (L) such as [CuL4Cl]Cl (I), [CuL4(NO3)2] (II) and [CuL3SO4] (III), have been synthesized. The compounds have been investigated by means of single-crystal X-ray diffraction, UV–Vis and IR spectroscopy, and static magnetic susceptibility measurements. The exchange interactions between unpaired electrons in copper(II) exhibit
