Tungstic acid-functionalized MCM-41 as a novel mesoporous solid acid catalyst for the one-pot synthesis of new pyrrolo[2,1-a]isoquinolines
Tungstic acid-functionalized MCM-41 (MCM-41–HWO4) was prepared, characterized and applied as a reusable mesoporous catalyst for the one-pot synthesis of new pyrrolo[2,1-a]isoquinoline derivatives.
