Abstract
The first base-mediated intermolecular cyclization of arylaldehydes and terminal arylacetylenes for the synthesis of a wide range of pyrroles in a single step has been described. The developed methodology used commercially available starting materials and tolerated a broad range of functional groups affording 2,3,5-triaryl-substituted-1H-pyrroles with good yields (up to 92% yield) under mild conditions. The possible mechanism was also discussed.

Abstract
This review article features selected examples on the synthesis of functionalized pyrroles that were reported between 2014 and 2019. Pyrrole is an important nitrogen-containing aromatic heterocycle that can be found in numerous compounds of biological and material significance. Given its vast importance, pyrrole continues to be an attractive target for the development of new synthetic reactions. The contents of this article are organized by the starting materials, which can be broadly classified into four different types: substrates bearing π-systems, substrates bearing carbonyl and other polar groups, and substrates bearing heterocyclic motifs. Brief discussions on plausible reaction mechanisms for most transformations are also presented.

Abstract
Over the past two decades, polyoxometalates (POM) have received considerable attention as solid catalysts, due to their unique physicochemical characteristics, since, first, they have very strong Bronsted acidity, approaching the region of a superacid, and second, they are efficient oxidizers that exhibit rapid redox transformations under fairly mild conditions. Their structural mobility is also highlighted, since they are complex molecules that can be modified by changing their structure or the elements that compose them to model their size, charge density, redox potentials, acidity, and solubility. Finally, they can be used in substoichiometric amounts and reused without an appreciable loss of catalytic activity, all of which postulate them as versatile, economic and ecological catalysts. Therefore, in 2009, we wrote a review article highlighting the great variety of organic reactions, mainly in the area of the synthesis of bioactive heterocycles in which they can be used, and this new review completes that article with the contributions made in the same area for the period 2010 to 2020. The synthesized heterocycles to be covered include pyrimidines, pyridines, pyrroles, indoles, chromenes, xanthenes, pyrans, azlactones, azoles, diazines, azepines, flavones, and formylchromones, among others.

Abstract
The evaluation of the significance of a chemical transformation addresses many factors, including such important characteristics as the number of chemical bonds formed in one step, the reaction time, labour intensity, the cost of reactants and catalysts and so on. The amount of waste produced in the reaction has also gained increasing importance in recent years. Multicomponent reactions (MCRs) occupy a special place as a synthetic tool in modern organic chemistry. These reactions allow the synthesis of target products with complex structures, minimizing labour costs. This review summarizes the literature on multicomponent reactions involving five or more components. The data in the review are classified according to the number of reactants participating in the reaction and the types of reactions. It is worth noting that in some cases, these transformations can be a part of a domino process, making this classification difficult, if not impossible. The structural diversity of the reaction products greatly increases with increasing number of components involved in the MCR, which becomes virtually unlimited when using combinations of MCRs. This review highlights the main trends of past decades in the field of MCRs. The last two decades have witnessed an explosive growth in the number of publications in this area of chemistry.
The bibliography includes 309 references.

Abstract
Multi-Component Reactions (MCRs) have emerged as an excellent tool in organic chemistry
for the synthesis of various bioactive molecules. Among these, one-pot MCRs are included, in
which organic reactants react with domino in a single-step process. This has become an alternative
platform for the organic chemists, because of their simple operation, less purification methods, no side
product and faster reaction time. One of the important applications of the MCRs can be drawn in carbon-
carbon (C-C) and carbon-heteroatom (C-X; X = N, O, S) bond formation, which is extensively
used by the organic chemists to generate bioactive or useful material synthesis. Some of the key carbon-
carbon bond forming reactions are Grignard, Wittig, Enolate alkylation, Aldol, Claisen condensation,
Michael and more organic reactions. Alternatively, carbon-heteroatoms containing C-N, C-O,
and C-S bond are also found more important and present in various heterocyclic compounds, which
are of biological, pharmaceutical, and material interest. Thus, there is a clear scope for the discovery
and development of cleaner reaction, faster reaction rate, atom economy and efficient one-pot synthesis
for sustainable production of diverse and structurally complex organic molecules. Reactions that
required hours to run completely in a conventional method can now be carried out within minutes.
Thus, the application of microwave (MW) radiation in organic synthesis has become more promising
considerable amount in resource-friendly and eco-friendly processes. The technique of microwaveassisted
organic synthesis (MAOS) has successfully been employed in various material syntheses,
such as transition metal-catalyzed cross-coupling, dipolar cycloaddition reaction, biomolecule synthesis,
polymer formation, and the nanoparticle synthesis. The application of the microwave-technique in
carbon-carbon and carbon-heteroatom bond formations via MCRs with major reported literature examples
are discussed in this review.
