Oxazolines as chiral building blocks for imidazolium salts and N-heterocyclic carbene ligands.

Frank Glorius1, Gereon Altenhoff, Richard Goddard, Christian Lehmann.   

Abstract

Enantiomerically pure imidazolium triflates can be readily prepared from bioxazolines and oxazolineimines; deprotonation of imidazolium triflate 2 gives a chiral N-heterocyclic carbene that can act as a ligand in a catalytically active palladium complex.
