“…Catalysis plays an increasingly crucial role in chemical processes and is widely used at the heart of the innumerable chemical methodologies from scientific research in academic laboratories to economical research in industrial laboratories . The easy recovery of the catalysts and their reusability can be regarded as the most significant issues facing the modern catalytic processes due to the fact that either the employed catalysts are often very expensive or the targeted products are often very valuable .…”

Molecules that contain polyhydroquinoline structural scaffolds are N‐containing heterocycles which are of great interest to organic chemists and biologists. Polyhydroquinoline structural scaffolds which are known as calcium channel blockers have emerged as one of the most important class of drugs used for the treatment of cardiovascular and Alzheimer's diseases. Besides, recovery and reusability of catalysts are important issues to be discussed in modern catalysis research especially in organic synthesis. The concept of magnetically recoverable catalysts has been rapidly developed in recent times. Magnetic separation is an efficient strategy for the rapid separation of catalysts from the reaction medium. Also, an alternative to time‐, solvent‐, and energy‐consuming separation techniques. In this review, we focused on the fabrication, surface‐modification and characterization of nanomagnetic materials and their application, as magnetically recoverable catalysts, in the synthesis of polyhydroquinoline structural scaffolds.

“…These materials serve as an exceptional choice for such applications. Moreover, they offer high specific surface areas, large and defined pore sizes, defined surface acidity, and excellent mechanical and thermal stability . In this regard, the substituents such as aluminum, titanium and zirconium can be incorporated into the silica framework to obtain materials for applications such as catalysis and ion exchange.…”

“…Moreover, they offer high specific surface areas, large and defined pore sizes, defined surface acidity, and excellent mechanical and thermal stability. [13][14][15][16] In this regard, the substituents such as aluminum, titanium and zirconium can be incorporated into the silica framework to obtain materials for applications such as catalysis and ion exchange. Among the metal-substituted mesoporous materials, aluminum-incorporated mesoporous materials have great potential in moderating acid-catalyzed reactions for large molecules.…”

Heterogeneous nanoscale catalyst was successfully synthesized via anchoring of V‐bis(2‐aminobenzamide) complex on the Al‐SBA‐15. This modified mesoporous was identified by several characterization techniques, such as X‐ray diffraction, field emission‐scanning electron microscopy, Fourier transform‐infrared, Brunauer–Emmett–Teller and transmission electron microscopy. V‐Bis(2‐aminobenzamide)@Al‐SBA‐15 was found to be an efficient heterogeneous catalyst for the rapid and desirable synthesis of various spirooxindole dihydroquinazolinones derivatives. In addition, the heterogeneous nanocatalyst was chemically stabilized in organic and aqueous solutions as well as can be expeditiously reused for at least seven cycles without a significant loss in catalytic activity.
