Simple and efficient synthesis of novel thiazolo[4,5-e]indole derivatives via three-component reaction
摘要
A series of thiazolo[4,5-e]indole derivatives have been obtained by a three-component domino reaction of 2-methylbenzo[d]thiazol-5-amine, arylglyoxal monohydrates and cyclohexane-1,3-dione in ethanol medium at 80°C catalyzed by acetic acid. Notable features of this synthesis are mild reaction, high synthesis efficiency, simple post-treatment operation and only water is generated as a byproduct.
