A new synthetic approach towards (±)-N-Boc-pregabalin is reported in this paper, which involves hetero-Diels-Alder addition of 3-nitrosoacrylate to ethyl vinyl ether and subsequent reduction of the C=N double bond of adduct, alteration of the ester functionality and reductive N-O bond scission followed by oxidation of the alcohol thus produced.
