Abstract

Furans represent an important class of five-membered heterocycles that are prevalent in a number of biologically active natural products and pharmaceuticals.[1] They are also useful building blocks in organic synthesis.[2] Thus, many synthetic methods [3] have been developed for the synthesis of furan rings, such as the condensation of 1, 4-dicarbonyl compounds (Paal–Knorr synthesis)[4] and the Feist–Benary synthesis.[5] However, these ...
