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.

A novel transition-metal-free three-component reaction for the construction of imidazo[1,2-a]pyridines has been developed. It represents a facile approach for the formation of C-N, C-O, and C-S bonds from ynals, pyridin-2-amines, and alcohols or thiols.
