α-azido esters by Mitsunobureaction with HN3. Optimization of this reaction was shown to proceed at room temperature with high chemical yield using 1,1-(azodicarbonyl)dipiperidine (ADDP) and trimethylphosphine (PMe3). Complete inversion of configuration was observed at the α-carbon. Several α,α-disubstituted amino acids were synthesized in high overall chemical yield and optical purity.
