operationally simple and one-pot multi-component approach has been developed for the construction of pyrazolyl-thiazoles using sulfamic acid (H2NSO3H) as a green catalyst in water. The notable features of this protocol include mild reaction conditions, enhanced selectivity with good yields and wide substrate scope, which makes it an attractive and useful process for the synthesis of biologically important
已开发出一种有效,操作简单且一锅多组分的方法,用于使用氨基磺酸(H 2 NSO 3 H)作为水中的绿色催化剂来构建吡唑基-噻唑。该方案的显着特征包括温和的反应条件,提高的选择性,良好的收率和广泛的底物范围,这使其成为合成生物学上重要的新型吡唑基-噻唑化合物的有吸引力且有用的方法。合成了一系列化合物(4a–z),并评估了它们对三种人类癌细胞系的细胞毒活性。其中,4b,4c和4e具有IC 50的相当大的细胞毒性。 值<5μM。
