Smiles rearrangement in Ugi- and Passerini-type couplings with electron-deficient phenols allows very straightforward multicomponent formation of O-aryl- and N-arylamides. Best yields were observed with the highly activated o- and p-nitrophenols, salicylic derivatives giving adducts in lower yields. The scope of these new reactions is further increased by the successful couplings of heterocyclic phenols

The four-component couplings of isocyanides with amines, aldehydes and phenols (Ugi–Smiles reactions) can be performed in water as the solvent instead of methanol or toluene.
