“…As reported in several reviews, the use of Suzuki, Stille and Heck coupling reactions is indispensable for the synthesis of high‐value chemicals such as natural products, agrochemicals, pharmaceuticals, polymers, biologically active compounds and advanced materials . These reactions benefit from the low toxicity and commercial availability of boronic acid, boronate ester derivatives or triphenyltin chloride and alkene sources …”

A boehmite@tryptophan-Pd nanoparticulate catalyst was prepared by a simple, fast and convenient route. The nanomaterial was characterized using various techniques and employed as a thermally stable catalyst for Heck, Stille and Suzuki cross-coupling reactions. Optimized conditions for these reactions are described. The catalyst could be isolated, post-reaction, by simple filtration and recycled for several consecutive cycles without a notable change in its activity.

“…Carbon nanotubes (CNTs) are common catalyst support, as they possess superior properties of high aspect ratio, high chemical stability, high electrical and thermal conductivity [24,25]. However, its seamless tubular structure offers few functional groups for tethering, and extensive breaking of the C-C bonds would cause its disintegration [26].…”

L-proline is directly loaded on the multi-wall carbon nanotubes (MWCNTs) with exceptionally high loading content of 67 wt.%. The obtained L-proline/MWCNTs catalyst is on par with the catalytic activity of free L-proline, even after 7 rounds of recycling and reusing. The excellent activity of L-proline/MWCNTs in typical Aldol reaction, Mannich reaction, Michael reaction, α-oxyamination reaction, and Knoevenagel condensation shows a broad applicability of the composite catalyst in different reactions and solvent systems. We believe that the unusual loading mode may open a window for designing heterogenized organo-catalysts.

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.
