and simple synthesis of 1, 3-disubstituted pyrrolo[1, 2-α]pyrazines from substituted 1H-pyrrole- 2-carbonitriles and arylboronic acids was developed. It’s a palladium(II)-catalyzed cascade reaction involving C(sp)–C(sp2) coupling followed by intramolecular C–N bond formation. The method can tolerate various substrates with satisfactory yields.
