  铜（II）盐对同炔丙基硫属元素化物的环化：2,3-二氢硒代苯，3-芳硒代苯和3-卤代硒基/噻吩的选择性合成

  摘要：

  铜（II）卤化物介导的高炔丙基硫属元素化物的环化反应产生了三种类型的硫属元素衍生物。通过控制溶剂，温度和气氛来实现选择性产物的形成。通过在室温和环境气氛下于室温下使用CuBr 2和1,2-二氯乙烷，可制得4-溴二氢硒苯衍生物，而CuBr 2和1,2-二氯乙烷在回流条件下产生选择性2-取代的硒烯。当1,2-二氯乙烷被二甲基乙酰胺代替时，仅获得3-卤代硒代苯。还通过在Sonogashira条件下3-卤代亚硒基与末端炔烃的反应研究了硫属芴的多功能性，从而提供了交叉偶联的产物。此外，3-卤代亚硒基与硼酸的反应以良好的收率得到了相应的铃木型产物。

• The potential antioxidant activity of 2,3-dihydroselenophene, a prototype drug of 4-aryl-2,3-dihydroselenophenes

  Here we present our results in palladium cross-coupling reaction of aryl boronic acids with 4-iodo-2, 3-dihydroselenophene derivatives. The cross-coupled products were obtained in satisfactory yields. A dehydrogenation of 4,5-diphenyl-2,3-dihydroselenophene was activated by DDQ and the 2,3-diarylselenophene was obtained in good yield. Regarding the antioxidant activity, the selenophene derivative 3a was effective in counteracting lipid and protein oxidation as well as scavenging ABTS radical. The findings of the present study indicate that 3a is a prototype for future drug development programs to treat disorders mediated by reactive oxygen species. (C) 2011 Elsevier Ltd.

  The synthesis of several highly functionalized 2,3-dihydroselenophenes from homopropargyl selenides via electrophilic cyclization is described. Electrophiles such as 12, ICI, and PhSeBr were used in a simple process employing CH2Cl2 as solvent at room temperature, which gave the cyclized products in high yields. 4-lodo-2,3-dihydroselenophenes obtained by this methodology were submitted to a dehydrogenation reaction using 2,3-dichloro-5,6-dicyanobenzoquinone (DDQ) to give 3-iodoselenophenes. 4-lodo-5-phenyl-2,3-dihydroselenophene was also submitted to the thiol copper-catalyzed and Heck-type reactions giving the desired products under mild reaction conditions.
