Abstract

ZrCl(4) was found to be an ideal catalyst to promote aza-Henry reactions between trifluoromethyl aldimines and some nitro alkanes giving new fluorinated β-nitro amines. The reaction is strongly influenced by the CF(3) group, the yield by the alkyl chain of the nitro compound, while the stereochemical outcome seems to be unaffected, the anti isomer being always the major product.
