Abstract: Abstract A mild, catalytic method for the synthesis of 3-carboxy-2,5-disubstituted furans is reported proceeding via a 5-exo-dig cycloisomerization reaction. The iron(III) chloride-catalyzed transformation of aryl- and alkyl β-ketoesters enables synthetic access to functionalized furan core… read more here.

Abstract: The catalytic activity of a series of [(AuCl)2(μ-PP)] (PP = 1,1'-bis(phosphino)metallocene ligands) compounds in the presence of Na[BArF24] (BArF24 = tetrakis(3,5-bis(trifluoromethyl)phenyl borate)) was examined in the formation of disubstituted furans from pyridine-N-oxide and terminal alkynes.… read more here.
