由三甲基硅基重氮甲烷和酰基异氰酸酯原位合成的2-取代4-(三甲基硅氧基)恶唑与乙酰二甲酸二甲酯或丙酸乙酯进行Diels-Alder反应，高产率地合成了呋喃-3，4-二羧酸酯或呋喃-3-羧酸酯。
The Diels-Alder reaction of 2-substituted 4-(trimethylsilyloxy)oxazoles, which were prepared in situ from trimethylsilyldiazomethane and acyl isocyanates, with dimethyl acetylenedicarboxylate or ethyl propiolate gave furan-3,4-dicarboxylic or furan-3-carboxylic esters in good yields.
