摘　　要：应用双对-甲氧苯基氧化碲（BMPTO）催化合成呋喃、噻吩杂环查尔酮，反应具有较好的立体选择性，所有产物经熔点、IR、^1HNMR分析证实为E-型异构体。产物收率为80%～94%。Some hetrocyclo substituted chalcones have been synthesized by condensation of the substituted benzaldehydes with corresponding compounds with active methylene group in the presence of bis (p-methoxy phenyl) telluroxide (BMPTO) as catalyst. The yields were 81%～94%. The melting points, IR and ~1H NMR spectra of the products show that they are all E-isomers.
