investigation on the versatility of 4,4-dimethyl-2-oxazoline derivatives, we present a straightforward synthesis of chiral lactone pheromones from readily available starting materials. As an application, we describe the diastereoselective synthesis of cis and trans-2-methyl-5-hexanolide (1), a pheromone component of the carpenter bee Xylocopa hirutissima, and a formal synthesis of (4R,5Z)-5-tetradecen-4-olide
作为我们正在进行的有关4,4-二甲基-2-恶唑啉衍生物多功能性研究的一部分,我们提出了从容易获得的起始原料直接合成手性内酯信息素的方法。作为一种应用,我们描述了顺式和反式-2-甲基-5-己内酯的非对映选择性合成(1),木匠蜜蜂Xylocopa hirutissima的信息素成分,以及(4 R,5 Z)-5-的形式合成。tetradecen-4-olide(2),日本甲虫Popillia japonica的性信息素。
