New heterocyclic scaffolds can be easily prepared by the coupling of heteroaromatic phenols (pyridines, pyrimidines) with carbonyl compounds, amines, and isocyanides. This transformation related to the Ugi reaction probably involves a Smilesrearrangement. The scope of this methodology is further extended by the successful use of heterocyclic thiols to form highly functionalized thioamides.
