O afforded primary selenocarboxylic amides. The cyclization of these compounds with α-halo ketones afforded a variety of functionalized 1,3-selenazoles. Theuse of P 2 Se 5 also allowed the convenient synthesis of selenocarboxylic diamides which were transformed into bis(selenazol-2-yl)alkanes ('bis-selenazoles'). A practical method for the synthesis of selenourea was developed. This useful small building
在 EtOH-H 2 O 存在下腈与 P 2 Se 5 的反应得到伯硒代羧酸酰胺。这些化合物与 α-卤代酮的环化得到了多种功能化的 1,3-硒唑。使用 P 2 Se 5 还可以方便地合成硒代羧酸二酰胺,该二酰胺被转化为双(硒唑-2-基)烷烃(“双硒唑”)。开发了一种合成硒脲的实用方法。这种有用的小结构单元成功地应用于伯2-氨基-1,3-硒唑的合成。

Based on a homology-modeled structure of PLTP and characteristic structural features of reported cholesteryl ester transfer protein (CETP) inhibitors, we designed and synthesized a novel series of 2,4,5-trisubstituted selenazole compounds. Biological evaluation reveals that compounds 12 and 17 exhibit favorable PLTP activity, and their IC(50)s are 8 mu M and 10 mu M, respectively. (C) 2010 Elsevier Ltd. All rights reserved.
