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

ABSTRACT

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.
