The Passerini reaction between arylglyoxals 1, isocyanides 2, and cyanoacetic acid affords N-substituted 3-aryl-2-cyanoacetoxy-3-oxopropionamides 3, which are cyclized in the presence of triethylamine to give N-substituted 3-aryl-4-cyano-2,5-dihydro-5-oxofuran-2-carboxamides 4
芳基乙醛 1、异氰酸酯 2 和氰基乙酸之间的 Passerini 反应生成 N-取代的 3-芳基-2-氰基乙酰氧基-3-氧代丙酰胺 3,在三乙胺存在下环化生成 N-取代的 3-芳基-4-氰基-2,5-二氢-5-氧代呋喃-2-甲酰胺 4
