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.
