An efficient method for the preparation of tetrasubstituted furans, which contains a nitromethyl group at the 4-position, has been developed. The applications of 4-(nitromethyl)furans on the synthesis of highly functionalized bis(furyl)oxime were explored

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

A general and efficient method for the synthesis of a wide range of α-carbonyl furans is described here. The cyclization of enynone is catalyzed by AgBF4 in a fluorous biphasic system of perfluorodecalin and N,N-dimethylformamide. A variety of chain ketone and cyclic ketone substrates were used to investigate the scope of the reactions.

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
Regioselective synthesis of multisubstituted furans via metalloradical cyclization of alkynes with α-diazocarbonyls: Construction of functionalized α-oligofurans

Co(III)-carbene radicals generated from activation of α- diazocarbonyls by Co(II)-porphyrin complexes have been shown to undergo a new type of tandem radical addition reaction with alkynes that affords five-membered furan structures. The Co(II) complex of
Rearrangement of propargylic esters: Metal-based stereospecific synthesis of (E)- and (Z)-knoevenagel derivatives

Alkoxy-substituted propargylic esters undergo regioselective 1,3-acyloxy migration in the presence of Pt(II) and Cu(I) catalysts, allowing the preparation of α-ylidene-β-keto and -malonate esters. The reaction proved to also be stereodivergent as the Pt(II) and the Cu(I) catalysts perform the isomerization with complementary Z/E selectivity. Moreover, alkynyl-conjugated Knoevenagel products are produced from (bisalkynyl)methyl acetates. In such a case, the reaction is chemoselective as the 1,3-acetyl migration takes place through the alkoxyalkyne group in preference over the phenylalkyne group. The resulting (E)-alkynylenone unit suffers metal-catalyzed cyclization into the furyl ring, generating a copper(I) carbene species. Copyright
