Cellulose-supported copper(0) efficiently catalyzes aza-Michael reactions of N-nucleophiles, such as amines and imidazoles with α,β-unsaturated compounds to produce the corresponding β-amino compounds and N-substituted imidazoles in excellent yields. The recovered catalyst can be used for several cycles with consistent activity.
