The rhodium-catalyzed intramolecular hydroaminomethylation reaction, generating 4-aryl-2,3-dihydropyrroles, has been developed. Triphenylphosphine has been proved to be the excellent ligand to prepare the dihydropyrrole derivatives in up to 99% yield. This procedure provides an efficient and simple alternative route to synthesize 4-aryl-2,3-dihydropyrrole derivatives only in one step.
Imidazolidine-2,4-dione derivatives of formula (I):
These compounds have anti-proliferative activity and are useful for treating pathological states and diseases linked to an abnormal cell proliferation, such as cancer.
