A conversion of o-phenylenediamines into benzotriazoles was achieved at room temperature using tert-butyl nitrite. The optimized conditions are also well suited for the transformation of sulfonyl and acyl hydrazines into corresponding azides. This protocol does not require any catalyst or acidic medium. The desired products were obtained in excellent yields in a short span of time.

Page/Page column 13-15, (2008/06/13)
A process for the preparation of ω-alkoxycarbonylamino-α-aminoacids and α,ω orthogonally diprotected diaminoacids from α,ω-diaminoacids using 1- alkoxycarbonylbenzotriazoles as protecting agents is disclosed. In an alternative embodiment, carbamoylating agents in the presence of benzotriazoles are used instead of 1-alkoxycarbonylbenzotriazoles. This reaction is preferably applied to the preparation of ε- alkoxycarbonyllysines from lysine. A process for the preparation of t-butoxycarbonylbenzotriazoles and novel complexes of ω-alkoxycarbonylamino-α-aminoacids with benzotriazoles are also disclosed.
