A versatile method for the diversified synthesis of furans and arenofurans has been developed that proceeds through K2CO3-promoted cyclization between enols/1,3-dicarbonyl compounds and nitroolefins at reflux in EtOH. This facile method has been successfully employed in the synthesis of benzotrifuran derivatives, which are useful hole-transporting materials. This procedure also provides direct access to dioxa[5]helicenes. This reaction offers a broad substrate scope, uses an inexpensive base and environmentally benign solvent, and is operationally simple.

Li, Liang,Zhao, Mi-Na,Ren, Zhi-Hui,Li, Jianli,Guan, Zheng-Hui
experimental part, p. 532 - 540 (2012/04/04)
The FeCl3-catalyzed addition and cyclization of enamino esters with nitroolefins provides a straightforward and general method for the synthesis of tetrasubstituted NH pyrroles. This novel method tolerates a wide range of functionality, and allows for rapid elaboration of the nitroolefins into a variety of substituted pyrroles in good yields. Further, an efficient KOAc-promoted addition and cyclization protocol toward substituted furans has been described as well. Georg Thieme Verlag Stuttgart · New York.
