- The late-stage functionalization of a biomimetic foldamer such as a peptoid is a useful tool to achieve structural diversity. Herein, a facile method for the synthesis of triazole- or tetrazole-containing peptoids using post-synthetic modifications has been reported. On a resin-bound peptoid with a chloroalkyl side chain(s), substitution with nucleophiles (azide or cyanide) and the subsequent [3 + 2]-cycloaddition reaction were optimized. Peptoids with azide, triazole, and tetrazole functional groups could be readily synthesized and could potentially be utilized further for orthogonal bioconjugation or metal recognition.
