  A convenient one-pot Cu(I)-catalyzed strategy for regioselective synthesis of trisubstituted furan derivatives has been developed via (2-furyl) carbene complexes. This process has opened a new synthetic route to a variety of α-carbonyl furans using air as the oxidant affording furans in good yields.

  Ag(I)-catalyzed cascade reactions involving enynone cyclization and cross-coupling with phosphorus ylides have been achieved for the first time. Subsequent treatment of the reaction mixture with I2 afforded the corresponding (E)-α-alkenylfurans in 73–95% yields with excellent stereoselectively. A reasonable mechanism has been proposed.

  A magnetic nano‐supported Cu(I) catalyst was prepared and showed high activity for cyclization of ene‐yne‐ketone to synthesize furans. The catalyst was easily recovered from the reaction by using external magnets and reused 8 times without significant loss of its catalytic activity.
