Al2(SO4)3 IS AN EFFICIENT AND MILD ACID CATALYST FOR THE ONE-POT, FOUR-COMPONENT SYNTHESIS OF POLYHYDROQUINOLINE

Aluminium sulfate has mild acidity, yet the acidity of aluminium sulfate is not taken advantage of in organic synthesis. Here, we utilized aluminium sulfate for the first time in a multicomponent reaction for the synthesis of polyhydroquinoline. A four-component one-pot synthesis of polyhydroquinoli...
