DOI: 10.1039/C4CC08052A, CommunicationAudrey Dumoulin, Claudia Lalli, Pascal Retailleau, Geraldine Masson
Highly enantioselective electrophilic amination reaction of enecarbamates with dibenzylazodicarboxylate and oxygenated nucleophiles catalyzed by chiral phosphoric acids is reported. Subsequent reduction or oxidation of the resulting precursors of [small alpha]-hydrazinoimines leads to 1,2-diamines or [small alpha]-amino acid precursors, respectively, in excellent yields and enantioselectivities.
