Benzotriazol-1-yl-sulfonyl azide, a new crystalline, stable, and easily available diazotransfer reagent provides N-(α-azidoacyl)benzotriazoles convenient for N-, O-, C- and S-acylations. The efficient syntheses of various amides, azido protected peptides, esters, ketones and thioesters is reported together with a wide range of azides (including α-azido acids from α- amino acids in partially aqueous conditions) and diazo compounds.
Synthesis of α-amino acids by addition of putative azido radicals to α-methoxy acrylonitriles derived from aldehydes and ketones

α-Methoxy acrylonitriles, available from aldehydes and ketones, react with sodium azide in the presence of ceric ammonium nitrate to give azido nitrates; from these compounds, α-amino acids are obtained by sequential treatment with sodium acetate in acetic acid and then methanolic potassium carbonate, followed by hydrogenation.
