In the electromagnetic spectrum, the microwave radiation region is located between infrared
radiation and radio waves. Microwaves have wavelengths of 1 mm±1 m, corresponding to …

In this review, we report the important role of solvent-free conditions coupled with microwave
activation and their advantages in heterocyclic synthesis. This eco-friendly approach, which …

Microwave irradiation is becoming an increasingly popular method of heating which
replaces the classical one because it proves to be a clean, cheap, and convenient method …

The development of new strategies for synthesis of small-sized heterocycles has remained a
highly attractive but challenging proposition. An overview of the application of microwave …

Two separate strategies have been developed for the preparation of highly substituted
pyridines from 1, 2, 4-triazines via the inverse-electron-demand Diels− Alder reaction: a …

By adopting green chemistry principles and methodologies, researchers can devise new
processes to help protect the environment from further damage. In this book, eminent …

Abstract An uncommon aza-Diels-Alder reaction of electron-deficient azoalkenes and
electron-deficient 3-phenacylideneoxindoles was successfully developed for convenient …

The molecular mechanism for the Diels–Alder reaction of N-acyl-1-aza-1, 3-butadiene with
dimethylvinylamine has been studied using density functional theory methods. This …

A study on the behaviour of vinylpyrazoles, pyrazolyl imines and pyrazolyl hydrazones as
dienes or dipoles is reported. Cycloaddition of the aforementioned compounds with electron …

Recent applications of microwave technology in well-known cyclization reactions for
heterocyclic ring formation and in other important reactions such as nucleophilic substitution …
