Rose bengal photocatalyzed expeditious multicomponent synthesis of 3,4-dihydropyrimidin-2-(1H)-ones/thiones under visible light irradiation
The combination of visible light, a renewable and green energy source, and rose bengal, a non-toxic organic dye as a photoredox catalyst, is an easy and efficient method for synthesizing 3,4-dihydropyrimidin-2(1H)-ones/thiones in EtOH at ambient temperature in very short reaction time. The present work offers simple operation, easy workup, rapid conversion, and excellent product yields, while accommodating a wide range of substrates. Rose bengal-based photocatalytic approach permits foremost sustainability, which delivers economic and environmental rewards.
期刊介绍：
The Journal of Heterocyclic Chemistry is interested in publishing research on all aspects of heterocyclic chemistry, especially development and application of efficient synthetic methodologies and strategies for the synthesis of various heterocyclic compounds. In addition, Journal of Heterocyclic Chemistry promotes research in other areas that contribute to heterocyclic synthesis/application, such as synthesis design, reaction techniques, flow chemistry and continuous processing, multiphase catalysis, green chemistry, catalyst immobilization and recycling.
