As part of the ongoing search for pharmacologically active lead structures, the obtained structural diversity allows for the fast exploration of a large chemical space. Not surprisingly, the development of MCRs, leading to new structural frameworks or serving as key transformations in the total synthesis of natural products, has expanded rapidly over the last few decades. To date a multitude of new three- and four-component reactions have already been described; however, examples of ‘‘higher-order’’ MCRs where five or even more components are combined in a single reaction vessel are remarkably scarce. With the growing interest for biologically active small molecules at the end of the 20th century, the application of MCRs to create libraries of such small, drug-like molecules was investigated with a steadily increasing intensity by industry and academia as a result of its superiority over other approaches (i.e. the use of readily available starting materials, inexpensive and easy to carry out chemistry, broad product spectra, high diversity in few steps, ease of automation, etc). This tutorial review aims to critically describe the developments achieved in recent years, charting the ideas, challenges, and milestone reactions that were essential for the progress of this field.

کبری نیکوفر زهرا خادمی شیوا خانیPara-toluene sulfonic acid embedded on nano silica )ρ-TSA@nano SiO2( has been synthesized via a simple procedure and characterized by fourier transform infrared spectroscopy (FT-IR), energy-dispersive X-ray spectroscopy (EDX), and scanning electron microscopy (SEM) MorePara-toluene sulfonic acid embedded on nano silica )ρ-TSA@nano SiO2( has been synthesized via a simple procedure and characterized by fourier transform infrared spectroscopy (FT-IR), energy-dispersive X-ray spectroscopy (EDX), and scanning electron microscopy (SEM) techniques. The synthesized nanocatalyst has been utilized to accelerate the one-pot multicomponent condensation reaction of isatins, anilines, and acetone to obtain the corresponding 1'-aryl-2'-(2-oxoindolin-3-yl)spiro[indoline-3,5'-pyrroline]-2,3'-diones at water media under reflux conditions. Utilization of H2O as available and green solvent, excellent yields of products, short reaction times, avoidance of by-products which could be obtained via Aldol condensation of acetone, easily-handle, inexpensive, non-toxic, and heterogeneous nano acid catalyst are some advantageous of the reported method. The recovery and reusability of the nano catalyst has been examined for four runs without activity loss Manuscript profile
