Diastereoselective α-amination of N-tert-butanesulfinyl imidates has been developed using N-aryl (or N-tert-butyl) N-diphenylphosphinyldiazenes as nitrogen sources. The chiral 1-azaenolates derived from imidates undergo nucleophilic addition with diazenes to give α-hydrazino imidates in good yields.
