Abstract A three‐step synthetic route towards enantioenriched tricyclic tetrahydroquinoline derivatives has been investigated. The first step involved the assembly of 4‐amino‐tetrahydroquinoline core through asymmetric three‐component Povarov reaction benzyl ( E )‐prop‐1‐en‐1‐ylcarbamate and p ‐anisidine with aliphatic aldehydes various length bearing protected hydroxyl group. alcohol was then deprotected employed in an intramolecular a secondary amine moiety producing desired scaffolds.

An immobilized p-sulfonic acid calix[4]arene was synthesized on the surface of silica-coated Fe3O4 nanoparticles. Due to combination magnetic recovery and properties, it acted as a robust, safe environmentally friendly catalyst for one-pot synthesis Biginelli adducts under microwave irradiation solvent-free conditions. A series were obtained in moderate excellent yields, most importantly, could be easily recovered by an external magnet reused five times without significant loss catalytic activity (ca. 80% yield all reuses using 0.64 mol% catalyst).
