Abstract

1-(4-Arylazobenzoyl)benzotriazoles 2a-c react in aqueous acetonitrile at 20 °C with aminoxy acids 3a-c to give azodye-labeled aminoxy acids 4a-i in 65-80% yields. Similarly, reaction of Fmoc-protected aminoxy-dipeptides 6a-c with 2a gave azodye-labeled aminoxy peptides 7a-c in 55-65% yield.
