A simple synthetic procedure for the conversion of amines and hydrazines into substituted semicarbazides was developed. The initial condensation between the desired amine and phenyl chloroformate into phenyl carbamate is followed by the addition of hydrazine under basic conditions. The reaction is tolerable to a variety of functional groups, with mild conditions and high percent yields.
开发了一种简单的合成方法,用于将胺和肼转化为取代的氨基脲。所需的胺和氯甲酸苯酯之间最初的缩合成氨基甲酸苯酯,然后在碱性条件下加入肼。该反应可耐受各种官能团,条件温和,收率高。
