A synthesis of the insect toxin pederin (1) based upon the union of metallated dihydropyran 8 with the oxamate ester derivative 9 is described. Noteworthy features include (a) a new method for the construction of metallated dihydropyrans which tolerates heteroatom functionality and (b) a rhodium-catalyzed hydroboration reaction which enables stereocontrolled formation of the stereogenic centre at C10.
本研究描述了一种基于金属化二氢吡喃 8 与草氨酸酯衍生物 9 结合的昆虫毒素 pederin (1) 的合成方法。值得注意的特点包括:(a) 可容忍杂原子官能团的金属化二氢吡喃的新构建方法;(b) 铑催化的氢硼化反应,可立体控制 C10 处立体中心的形成。
