environmentally benign synthesis of 2-substituted benzothiazoles was developed through RuCl3-catalyzed oxidative condensation of 2-aminothiophenol with aldehyde in ionic liquid by using air as the oxidant. With this procedure, a series of 2-substituted benzothiazoles and benzothiazole/pyrimidine nucleoside hybrids with antimicrobial activities were efficiently prepared from easily accessible starting materials
通过使用空气作为氧化剂,通过RuCl 3催化2-氨基硫酚与醛在离子液体中的氧化缩合反应,开发了一种高效,实用且对环境有益的合成2-取代的苯并噻唑的方法。通过这种方法,可以从易于获得的起始原料中高效制备一系列具有抗菌活性的2-取代的苯并噻唑和苯并噻唑/嘧啶核苷杂化物。
