The synthesis of highly functionalized 3-nitrotetrahydro-furans starting from allylic alcohols and nitroalkenes through an efficient CuCl 2 -mediated tandem anionic/radical process is reported. The one-pot reaction consists of oxa-Michael addition/SET/radical 5-exo-cyclization-ligand transfer. Functionalization of the THF ring is facile and provides diverse substituted derivatives.
