An InâSiO2 composite was prepared by the solâgel method and was applied as a heterogeneous Lewis acid catalyst in the multicomponent Hantzsch synthesis of symmetrical and non-symmetrical 1,4-DHPs. The Ca2+ channel blockers nifedipine and nemadipine B were synthesized in a single step through a solvent-free protocol.
