Fecha de publicación: | 2011 | Editor: | Elsevier | Citación: | Tetrahedron 67: 624- 635 (2011) | Resumen: | The immune response to regioisomeric haptens of azoxystrobin with varied derivatization sites was studied. Based on the Sonogashira and Suzuki-Miyaura couplings and following a straightforward modular design, we have synthesized four haptens with the same linker anchored through C-C bonds and located at different sites of the molecule. The most stereoselective antibodies were produced from immunogens with the spacer arm at a distal position from the β-methoxyacrylate moiety characteristic of strobilurins. Moreover, we observed that assay cross-reactivity was reliant on the functionalization site of the competitor derivative. Finally, the antibody binding site was explored using synthetic chemical analogues. | URI: | http://hdl.handle.net/10261/112277 | DOI: | 10.1016/j.tet.2010.11.054 | Identificadores: | doi: 10.1016/j.tet.2010.11.054 issn: 0040-4020 |
