Amberlyst 15®: An Efficient Green Catalyst for the Synthesis of Heterocyclic Compounds

Amberlyst 15 (A-15) is one of the most common heterogeneous catalysts in organic synthesis. Since its development 1962, A-15 has proved to be a highly efficient green catalyst many reactions that require acid catalysis. In last two decades, reports had been issued focused on use as heterocyclic The implies advantages being inexpensive, non-toxic, easily handled, and separable from reaction mixture. Other include easy separation products recyclability. latter useful sustainable chemistry. present review summarizes applications synthesis heterocycles during decade (from 2010 till 2019). classified according ring size with focus mechanism catalyzed by A-15.
