异氰基乙酸乙酯是一种有机化合物,化学式为C5H7NO2。根据一份2020年的统计,它是在学术研究中第五常见的异腈。[3]它可由N-甲酰基甘氨酸乙酯和光气(或三氯氧磷[4])在三乙胺存在下于二氯甲烷中反应得到。[2]
反应
异氰基乙酸乙酯在催化下和乙醛反应,可以得到4,5-二氢-5-甲基-4-𫫇唑甲酸甲酯,反应同时产生4S-反式异构体和4R-顺式异构体,比例84:16。[5]它和己醛在对甲苯磺酸钠存在下于水中反应,可以得到N-(2-羟基-1-氧代庚基)甘氨酸乙酯。[6]
- CNCH2COOC2H5 + KOH → CNCH2COOK + C2H5OH
它和磺酰氯在三氯甲烷中反应,可以得到N-二氯亚甲基甘氨酸乙酯。[8]
在氯化铜、邻菲啰啉和碳酸铯存在下,它和芳胺、二氟氯乙酸钠反应,可以得到相应的芳基咪唑甲酸乙酯。[9]
