As already documented for other azoles, methods for transition metal-mediated approaches to imidazoles with different substitution pattern have been disclosed recently, (a) In the Pd-catalyzed multicomponent approach, N-alkylimines, acid chlorides and N-tosylimines are coupled in the presence of a phosphine, DIPEA/LiCl, carbon monoxide, and a specific Pd(0) catalyst to give tetrasubstituted N-alkylimidazoles 48 [398] ... [Pg.226]
