GC/EI-MS, at different moments of the insect life span, highlighted the growing trend of their secretion. While for the synthesis of saturated esters, conventional transesterification methods could be adopted, for the synthesis of unsaturated components, a Negishi cross-coupling between organozinc halides and (Z)-1-bromo-1-alkenes was developed. To the extent of our knowledge, this reaction represents
在本研究中,合成并鉴定了从橄榄果蝇雌性直肠提取的11种新的性别特异性成分。在昆虫生命周期的不同时刻,通过GC和GC / EI-MS对这些成分进行定量测定,突显了它们分泌的增长趋势。虽然对于饱和酯的合成,可以采用常规的酯交换方法,但是对于不饱和组分的合成,开发了有机锌卤化物与(Z)-1-溴-1-烯烃之间的Negishi交叉偶联。据我们所知,该反应代表了烷基锌试剂与烯基卤化物之间负载型催化剂促进的Negishi偶联的第一个例子。
