• A phase-switch purification approach for the expedient removal of tagged reagents and scavengers following their application in organic synthesis

  日期：——

  In this paper we wish to report on a variety of expedient chemical transformations and purifications achieved via a generic ‘catch and release’ methodology, based on a synthetically inert bipyridyl chelating tag that can be selectively captured with a resin-bound copper(II) species. Utilising this approach we are able to derive many of the same benefits associated with both solid phase synthesis and supported reagent methods.

  本文旨在报道通过一种基于合成不活跃的双吡啶螯合标签的通用“捕获与释放”方法，实现的一系列便捷的化学转化和纯化。该方法可以选择性地利用树脂结合的铜(II)物种来捕获双吡啶螯合标签。采用这种方法，我们能够获得与固相合成和支持试剂法相关的许多相同益处。
