Regioselective Synthesis of Multisubstituted Furans via Copper-Mediated Coupling between Ketones and β-Nitrostyrenes
摘要:
A copper-mediated intermolecular annulation of alkyl ketones and beta-nitrostyrenes has been developed for the regioselective synthesis of multisubstituted furan derivatives in good yields. This protocol is applicable to both cyclic and acyclic ketones.

A novel copper-mediated annulation of alkyl ketones with alpha,beta-unsaturated carboxylic acids has been accomplished. This reaction provides a facile and regio-defined method for the synthesis of 2,3,5-trisubstituted furans from simple chemical reagents.
