a safe method in which highly unstable O-mesitylsulfonylhydroxylamine (MSH) can be prepared and consumed in continuous flow. MSH was prepared in situ and used for the flow amination of a range of pyridines, which were subsequently transformed into useful pyrazolopyridine building blocks.
该论文展示了一种安全的方法,在该方法中,高度不稳定的 O-甲基磺酰基
羟胺 (MSH) 可以在连续流动中制备和消耗。MSH 是原位制备的,用于一系列
吡啶的流动胺化,随后将其转化为有用的
吡唑并
吡啶结构单元。
