Using iodine to induce the intermolecular thioamination reaction of maleimide, thiol and amine, various kinds of substituted 3-amino-4-thiomaleimides were obtained in good yields. This reaction was performed in THF at the presence of I2 and TBHP. On the basis of optimized conditions, a variety of thiophenols and amines were involved in the reaction. The method provided a new and green way for the thioamination
用碘诱导马来酰亚胺、硫醇和胺的分子间硫胺化反应,以良好的收率获得了各种取代的3-氨基-4-硫代马来酰亚胺。该反应在 I 2和 TBHP存在下在 THF 中进行。在优化条件的基础上,多种苯硫酚和胺类参与反应。该方法为马来酰亚胺的硫胺化反应提供了一种新的绿色途径,避免了重金属的使用。
