A new alternative system for the chemoselective oxidation of secondary hydroxyl group to ketone with IBX/n-Bu4NBr in CH2Cl2–H2O has been developed. Under the reaction conditions, the secondary hydroxyl group was highly chemoselectively oxidized to the corresponding ketone, in moderate to good yields at rt, in the presence of primary hydroxyl group within the same molecule.
开发了一种新的替代系统,用于在CH 2 Cl 2 -H 2 O中用IBX / n -Bu 4 NBr将仲羟基化学选择性氧化为酮。在反应条件下,在同一分子内存在伯羟基的情况下,仲羟基在室温下以中等至良好的收率被高度化学选择性氧化为相应的酮。
