Fecha de publicación: | 19-mar-2007 | Editor: | Elsevier | Citación: | Tetrahedron: Asymmetry 18(5): 651-658 (2007) | Resumen: | The enantioselective synthesis of both enantiomers of (Z)-1,1,1-trifluoro-3-methyl-4-thia-13-octadecen-2-one and (Z)-1,1,1- trifluoro-3-methyl-4-thia-13-hexadecen-2-one (ee ≥ 90%), potential inhibitors of the pheromone action of two major maize pests Sesamia nonagrioides and Ostrinia nubilalis, is described. The key step is based upon a stereoselective alkylation with methyl iodide using the SAMP-/RAMP-chiral auxiliary methodology, followed by deprotection under non-racemization conditions. | Descripción: | 8 pages, 1 figure.-- Printed version published on Mar 30, 2007. | Versión del editor: | http://dx.doi.org/10.1016/j.tetasy.2007.02.022 | URI: | http://hdl.handle.net/10261/9459 | DOI: | 10.1016/j.tetasy.2007.02.022 | ISSN: | 0957-4166 | E-ISSN: | 1362-511X |
