A versatile radical based approach to O-alkylated hydroxylamines and oximes
Résumé
O-Alkylhydroxylamines, often used for the preparation of bioconjugates, can be readily obtained by radical addition to suitable O-alkenylhydroxylamine derivatives. In the case of N-Boc-O-allylhydroxylamine, the addition is unexpectedly followed by elimination resulting in an overall allylation of the radical species. © 2008 Elsevier Ltd. All rights reserved.
