N-terminal α-azido peptides and C-terminal peptideo-(diphenylphosphine)phenyl esters. Mass spectrometric analysis of the reaction mixture provided a better insight into the mechanism of the Staudinger ligation and has been used to explain the observed intermediates and to optimize the ligation reaction. As a result, the optimized reaction enables the chemoselective coupling of peptides containing amino
