摘要：

Ring in the new: A new annulation for the efficient synthesis of substituted furans and pyrroles is reported. The RhIII-catalyzed reaction of O-methyl α,β-unsaturated oximes with aldehydes and N-tosyl imines affords secondary alcohol and amine intermediates, respectively. Cyclization and aromatization occurs under the reaction conditions to provide access to biologically relevant furans and pyrroles in good yields. Cp*=C5Me5, DCE=1,2-dichloroethane, THF=tetrahydrofuran. Copyright © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
