N,N-Diethanolaminomethyl Polystyrene: An Efficient Solid Support to Immobilize Boronic Acids.
The key to the efficiency of N,N-diethanolaminomethyl polystyrene (DEAM-PS), the first solid support capable of coupling to boronic acids, is the formation of a stable, resin-bound boronic ester ate adduct (see scheme). With this resin it is now possible to efficiently immobilize a wide variety of boronic acids including functionalized ones that can be derivatized by solid-phase combinatorial synthesis.
