aldehydes were allowed to react in one-pot operation to give 2-aryl-benzothiazoles in excellent yields in the presence of Dowex 50W in water. Very high yields coupled with the ease of work-up procedure, formation of no side products, employment of “reusable” catalyst, and “green” synthesis in aqueous medium without maintaining anhydrous reaction conditions are the most important aspects of this methodology
在Dowex 50W的
水中,以一锅操作方式使2-
氨基
硫酚和各种芳基醛反应,以极好的收率得到2-芳基-
苯并噻唑。这种方法最重要的方面是非常高的收率,加上易于处理的过程,无副产物的形成,使用“可重复使用的”催化剂以及在
水性介质中进行“绿色”合成而不保持无
水反应条件,这是该方法学的最重要方面。J.杂环化学,(2009)。
