Novel one-pot synthetic protocol has been developed for obtaining 2, 3-disubstituted 1,4-benzothiazines with excellent yields, carrying cyclocondensation of 1,3-dicarbonyl compounds with substituted 2-(2-(2-aminophenyl)disulfanyl)benzenamines, under supramolecular catalysis of β-Cyclodextrin (β-CD) in water at neutral pH. The role of β-CD in accelerating the cyclocondensation has been demonstrated. This biomimic catalyzed route is simple, economic, relatively rapid and environmentally benign.
已经开发出一种新颖的一锅合成方法,用于高效制备2, 3-二取代的1, 4-苯并噻嗪,该方法涉及在β-环糊精(β-CD)的超分子催化下,中性pH值的水相中,将1, 3-二羰基化合物与取代的2-(2-(2-氨基苯基)二硫醚)苯胺进行环缩合反应。研究表明,β-CD在加速环缩合反应中发挥了作用。这种仿生催化途径简单、经济、相对快速且环境友好。
