以β-酮酯、芳醛和尿素/硫脲的Biginelli反应为基础，建立了3,4-二氢嘧啶-2-(1H)-酮/硫酮的绿色自由基合成方法。采用质子耦合电子转移（PCET）光催化剂在空气环境、室温和可见光条件下对乙醇溶液进行催化，提供了一种可再生能源。在这项研究中，我们寻求创造一种新的供体-受体（D-A）荧光团，价格合理，可广泛使用。咔唑基光催化剂（4CzIPN）除了具有省时和使用简单的能力外，还具有优异的产率，节能和生态友好性。这使得跟踪环境和化学因素的演变成为可能。为测定3,4-二氢嘧啶-2-(1H)-酮/硫酮的周转率（TON）和周转率（TOF），进行了研究。克级循环试验表明，该方法可有效地用于工业生产。以β-酮酯、芳醛和尿素/硫脲的Biginelli反应为基础，建立了3,4-二氢嘧啶-2-(1H)-酮/硫酮的绿色自由基合成方法。
Based on the Biginelli reaction of β-ketoesters, arylaldehydes, and urea/thiourea, we created a green radical synthesis procedure for 3,4-dihydropyrimidin-2-(1H)-ones/thiones. A PCET (proton-coupled electron transfer) photocatalyst was used in an ethanol solution in an air environment and at room temperature and visible light to provide a renewable energy source. In this study, we seek to create a novel donor–acceptor (D–A) fluorophore that is affordable and widely available. The carbazole-based photocatalyst (4CzIPN), in addition to its time-saving capabilities and simplicity of use, exhibits excellent yields, is energy-efficient, and is ecologically friendly. This makes it possible to track the evolution of environmental and chemical factors throughout time. To determine the turnover number (TON) and turnover frequency (TOF) of 3,4-dihydropyrimidin-2-(1H)-ones/thiones, a study was done. Gram-scale cyclization demonstrates that it may be used in industry effectively. Based on the Biginelli reaction of β-ketoesters, arylaldehydes, and urea/thiourea, we created a green radical synthesis procedure for 3,4-dihydropyrimidin-2-(1H)-ones/thiones.
