Microwave radiation, an electromagnetic radiation, is widely use as a source of heating in
organic synthesis. The basic mechanisms observed in microwave assisted synthesis are …

A simple, efficient and cost-effective method for the synthesis of 3, 4-dihydropyrimidin-2 (1H)-
one by a one-pot three-component cyclocondensation reaction of a 1, 3-dicarbonyl …

Potassium carbonate supported solventless synthesis of thiohydantoins under microwave
irradiation is described. The use of K2CO3 not only eliminates the need for external base to …

The use of microwave irradiation (MWI) as a nonconventional source of energy, a
consequence of converting electromagnetic energy, had become very attractive for its …

Modified Biginelli and Hantzsch reactions were carried using environmentally benign
processes. Neat reactants subjected to microwave radiation gave the required products …

Microwave (MW) radiation has been used in chemical analysis and chemical synthesis. MW
heating under controlled conditions offers distinct advantages over conventional heating …

A simple, green, and efficient approach was used to synthesize 3, 4-dihydropyrimidines
derivatives. We showed that the application of the planetary ball milling method with a ball-to …

Green chemistry is not an emerging trend, but is already a reality owing to its applications. A
large number of case studies are presented here in addition to literature work. The case …

Barbituric acid (pyrimidine-2, 4, 6 (1H, 3H, 5H)-trione) as odourless white crystals has been
prepared in 1864. Due to the acidity of the CH2 group, the pyrimidine ring of barbituric acid …
