title: Expeditious microwave-assisted synthesis of functionalized oxaphosphaphenanthrenes and chromenes via multicomponent reactions of trivalent phosphorus nucleophiles.
abstract: Stable derivatives of oxaphosphaphenanthrenes were prepared by using the reactions of dialkyl acetylenedicarboxylate with 3-bromo-2-naphthol in the presence of trimethyl or triphenyl phosphite under microwave conditions at 70°C in good yields. Under similar conditions, chromene derivatives were produced by using triethyl phosphite and dialkyl acetylenedicarboxylate in the presence of OH-acids in excellent yields.
