摘要: 最近,我们用碳酸钾作碱从碲盐在含微量甲酰胺的乙腈中,手室温条件下十分简便地合成了2-或2,4-不饱和腈,酮,酯和酰胺[1-3]。杂环查尔酮和5-硝基呋喃烯类化合物都是具有生理活性的化合物[4]。为扩大碲ylide的应用并研究杂环基团引入对碲ylide反应活性的影响,本文报道溴化2-喃甲酞甲基二丁基碲(1a)和溴化2-噻吩甲酸甲基二丁基碲(1b)两种碲盐与芳醛(2)的反应以期合成标题衍生物。

Abstract: By reaeting substituted heteroeyele tellttronium salts with aldehydes under mild conditions ccrresponding chalcones and alkadienones were obtained. In the presence of dibutyl telluride, 2-bromomethyl-5-nitrofuran condensed easily with aldehydes in THF to afford corresponding olefin derivatives in one-pot reaction.
