An efficient synthesis of differently substituted furans from acetylene dicarboxylates and β-dicarbonyl compounds is described. The furan nucleus was built by means of an Yb(OTf)3 catalyzed cycloaddition reaction yielding desired adducts in 91%-98% yield.
描述了一种由乙炔二羧酸酯和β-二羰基化合物高效合成不同取代呋喃的方法。呋喃环是通过Yb(OTf)₃催化的环加成反应构建的,所需加合物的产率为91%-98%。
