The continuous flow Norrish-Yang photocyclization of 1,2-diketones has been developed and used for the synthesis of a large number of functionalized 2-hydroxycyclobutanones, under blue light irradiation and employing acetone as a solvent. This eco-friendly procedure represents a valid alternative to the reactions carried out in batches thus reducing the reaction times, the formation of secondary products
1,2-二酮的连续流Norrish-Yang光环化已经开发出来,并用于在蓝光下并以
丙酮为溶剂,合成大量官能化的
2-羟基环丁酮。这种环保的方法代表了批量反应的有效替代方法,从而缩短了反应时间,减少了副产物的形成,并简化了纯化步骤。使用不同取代的二酮化合物使我们获得了范围广泛的2和3官能化的
环丁酮,因此可以评估该方法的范围和局限性。
