α-Azido carboxylic acids have recently emerged as versatile N-protected equivalents for α-amino acids, especially valuable when the sterically hindered Cα-dialkylated α-amino acids have to be incorporated. Unsymmetrically substituted Cα/s

A novel method for the SN2 reaction on quaternary carbon atoms using bis(p-nitrophenyl)phosphorazidate has been developed. Chiral tertiary alcohols were directly converted into the corresponding chiral tertiary azides with complete inversion of configuration. Several α,α-disubstituted α-amino esters or amino acids were prepared through the conversion of azides to the corresponding amines by catalytic hydrogenation.
