tri-, and tetrasubstituted pyrroles is described. This regioselective one-pot method relies on nucleophilic catalysis of the intermolecular addition of oximes to activated alkynes and thermal rearrangement of the in situ generated O-vinyl oximes to form pyrroles that contain a functional group handle at the C3/C4 position.
