“…The synthesis of 9-methoxynaphtho [1,2-b]benzofuran was achieved by reacting 1bromo-4-methoxy-2-nitrobenzene with two molar equivalents of 1-naphthol and potassium tert-butoxide in dry dimethyl sulfoxide (DMSO) under microwave (MW) irradiation for 2 h (Scheme 1). The replacement of conventional heating by microwave irradiation was reported to be a powerful tool for reducing the volume of solvent used, shortening reaction times and increasing the reaction yield, often associated with a decrease in by-products and for all these reasons also employed in the preparation of organic products for electronic devices [5].…”

A highly selective one-pot microwave-assisted synthesis of 9-methoxynaphtho[1,2-b]benzofuran was obtained by treating 1-naphthol with 1-bromo-4-methoxy-2-nitrobenzene and two molar equivalents of potassium tert-butoxide in dimethyl sulfoxide. The selectivity in the production of the title compound was addressed by the suitable position of the bromine and nitro group on the aryl reagent. Moreover, we highlight how the nitro group plays a dual role, as activator in the first nucleophilic substitution with the release of bromide ion and then as the leaving group in the furan cyclization. Eventually, the product was structurally characterized by MS and extensive NMR analyses.

Multi-component reactions for the construction of heterocycles have been fascinated by microwave energy as an alternative technique of heating, owing to the advantages over traditional reflux methods. The heterogeneous catalysts contribute significantly towards recycling, harmless, easy filtration, catalyst preparation, more life span, abundance, and product yields. With novel and creative uses in organic and peptide synthesis, polymer chemistry, material sciences, nanotechnology, and biological processes, the usage of microwave energy has rapidly increased during the past 20 years. This article covers multicomponent reactions involving construction of chromenes, pyridines, pyrroles, triazoles, pyrazoles, tetrazoles, trans and cis julolidines using heterogeneous catalysts under microwave. It provides an overview of contemporary microwave-assisted heterogeneous catalytic reactions. Microwave chemistry is now an established technology with several advantages regarding reaction rate and production yield, improving energy savings as confirmed by many applications. Due to the widespread curiosity in medicinal chemistry, the heterogeneously catalysed construction of heterocycles under microwave irradiation is explored to reduce time and energy. By considering various aspects of economy, eco-friendly, and user-friendly factors, this review focuses on recent advances in the multi-component construction of heterocycles using heterogeneous catalysts under microwave irradiation. This review also discusses the benefits and limitations of reaction conditions and yields from the literature reports for the past five years.

Currently, microwave radiation is widely used in various chemical processes in order to intensify them and carry out processes within the framework of “green” chemistry approaches. In the last 10 years, there has been a significant increase in the number of scientific publications on the application of microwaves in catalytic reactions and synthesis of nanomaterials. It is known that heterogeneous catalysts obtained under microwave activation conditions have many advantages, such as improved catalytic characteristics and stability, and the synthesis of nanomaterials is accelerated several times compared to traditional methods used to produce catalysts. The present review article is to summarize the results of modern research on the use of microwave radiation for the synthesis of heterogeneous catalytic nanomaterials and discusses the prospects for research in the field of microwave-induced liquid-phase heterogeneous catalysis in hydrogenation.
