摘要
以三氟甲磺酸镱（Yb（OTf）3）为催化剂,PEG-400为溶剂,靛红、β-环己二酮与丙二腈（或氰基乙酸乙酯）三组分于60℃反应30 min合成一系列螺环吲哚类衍生物,收率为87%~95%,其结构经^1H NMR和^13C NMR确证.Yb（OTf）3/PEG-400可回收套用五次.
A series of spiro[4H-pyran-oxindole]derivatives in yield of 87% - 95% was synthesized by the reaction of isatins,malononitrile or ethyl cyano-acetate,and 1,3-dicarbonyl compounds in the presence of catalytic amount of Yb（OTf）3 using PEG-400 as the solvent at 60℃ for 30 min.The structures were confirmed by ^1 H NMR and ^13 C NMR. It is proven that Yb（OTf）3/PEG-400 can be recycled for five times.
