General base-catalyzed double-Michael reactions of allenes with various dinucleophiles are described. The reactions are facilitated most efficiently by a catalytic amount of trimethylphosphine, affording six types of C2-functionalized benzannulated five-m

Benzo-condensed five-membered heterocyclic rings containing two heteroatoms have been synthesized starting from disubstituted benzenes and allenic derivatives.The structure of all products was corroborated by elemental analysis and ir and 1H nmr spectroscopy.
