room temperature, and various substituents (halogen, alkyl, aryl) and substituted products were obtained with 29 examples within 2 h. Large-scale synthesis and derivatization study via carbonyl reduction to produce easily modified hydroxyl groups and convenient N-Ts deprotection showed the potential utility of this strategy.
在无光催化剂的条件下实现了一般可见光诱导的磺酰化/环化以产生
喹啉-2,4-二酮。反应在室温下进行,2小时内得到29个实例的各种取代基(卤素、烷基、芳基)和取代产物。通过羰基还原产生易于修饰的羟基和方便的 N-Ts 脱保护的大规模合成和衍生化研究显示了该策略的潜在效用。
