intermediates that are useful for synthesizing a variety of terpenoid natural products; however, the results presented herein show that subtle differences in the structures of functionalized geranyl chlorides can significantly impact their abilities to function as effective electrophiles in synthetic reactions. A series of focused kinetics experiments identify specific structure–activity relationships
香叶醇的衍生物是多用途的合成中间体,可用于合成各种萜类天然产物。然而,本文给出的结果表明,官能化的香叶基氯的结构上的细微差异会显着影响其在合成反应中充当有效亲电试剂的能力。一系列集中的动力学实验确定了特定的结构-活性关系,这些关系不仅说明了空间体积的重要性,而且还说明了影响其整体反应性水平的分子遥远区域的电子效应的重要性。计算模型表明,在某些(但不是全部)构象中,填充物与填充物的轨道混合事件会导致反应物不稳定,这可能是这些重要电子效应的关键因素。
