Cyclic nitrones: oxidation studies and the synthesis of a heterocyclic nitrone
… yielding diglycollic acid and nitrous oxide. 1,3-Cycloaddition products were formed when the heterocyclic nitrone was heated together with cyclohexene, with phenylisocyanate and with ethyl acrylate. All the products incorporated the fused bicyclic skeleton of morpholino-isoxazolidine and were each …

Synthesis and testing of novel polypeptides for biological applications
… that can be reacted with an azide by the 1,3 cycloaddition "click" reaction. With this system, we can incorporate functional groups that are ordinarily difficult to introduce because of cross-reactions or exhaustive protection-deprotection steps. In addition, we can more directly mimic the …
