enol ethers and aryl acetals through oxonium intermediate under solvent-free conditions using heterogeneous solid acid catalysts. Among studied solid acid catalysts, Amberlyst-15 gave excellent yields (35–85%) of alkylated products. The catalyst showed broader substrate scope, and a recyclable catalytic cost-efficient approach of the alkylation was examined on the different types of cyclic enol ethers
