combination of I and bis(trichloromethyl)carbonate, the Swern oxidation of primary and secondary alcohols was significantly promoted under mild conditions, which afforded the corresponding aldehydes or ketones in good yields. It is noteworthy that the reoxidation of the isolated by-product sulfide V could be further recycled in Swern oxidation. GRAPHICAL ABSTRACT
摘要 设计并制备了一种新型亚砜4-(2-(2-(甲基亚磺酰基)乙基)-4-硝基苯基)-吗啉(I),收率良好。I与双(三氯甲基)碳酸酯结合后,在温和条件下显着促进了伯醇和仲醇的Swern氧化,从而以良好的收率得到相应的醛或酮。值得注意的是,分离出的副产物硫化物 V 的再氧化可以在 Swern 氧化中进一步循环使用。图形概要
