convenient synthesis of methyl α-iminotrifluoropropionate (methyl 3,3,3-trifluoro-2-iminopropanoate, 3), based on the aza-Wittig reaction of methyl trifluoropyruvate with triphenylphosphine imide, was developed. The synthetic potential of N-H imine 3, existing as equilibrium mixture (10:1) of E/Z isomers, in the preparation of functionalized acyclic and heterocyclic derivatives possessing a pharmacophoric
基于三氟丙酮酸甲酯与三苯基膦酰亚胺的aza-Wittig反应,开发了一种方便的α-亚氨基三氟丙酸甲酯(3,3,3-三氟-2-亚氨基丙酸甲酯,3)的合成方法。公开了在具有药效性三氟丙氨酸片段的官能化无环和杂环衍生物的制备中,以E / Z异构体的平衡混合物(10:1)存在的NH亚胺3的合成潜力。 NH亚胺-三氟丙酮酸-三氟丙氨酸-亚氨基羧酸酯-环化-亲核加成
