cyclopropylmethylcarbinyl tosylate participate in organocuprate substitution reactions; retention of configuration at the nucleofugal sp3-C atom and skeletal reorganizations are observed. A plausible mechanism for these reactions is discussed. Coupling of homogeranyl iodide with a four-carbon, functionalized, vinylic cuprate reagent is applied to stereospecific synthesis of trans, trans-farnesol.
胆固醇和5-降冰片-2-基甲苯磺酸酯的双键和环丙基甲基羰基甲苯磺酸酯的环丙烷环参与有机铜酸酯的取代反应;观察到在核真菌sp 3 -C原子处构型的保留和骨架重组。讨论了这些反应的合理机制。高碘烷基碘与四碳官能化乙烯基乙酸铜试剂的偶联被用于反式,反式-法呢醇的立体有择合成。
