A nickel-catalyzed tandem reaction of N-vinylamides with arylboronic acids and bromodifluoroacetate has been developed. The reaction efficiently furnishes a series of protected α,α-difluoro-γ-amino acid esters.

We describe the synthesis of rare coordination compounds of early transition metals with α-amino acids and α-amino acid esters, the unusual C–C dimerization ofl-proline, and the stabilization of reactive α-ammonium acylchloride cations.

The racemization rate of N- [p-nitrobenzylidene] -α-amino acid esters was found to be even thousand-fold smaller than that of the azlactones of N-acyl-α-amino acids. t-Butyl esters of N-[p- nitrobenzylidene]-α-amino acids are much more stable to racemization as the correspondent methyl esters.
