The Prelog-Djerassi lactone, a key intermediate for the synthesis of several medicinally important macrolide antibiotics, and protomycinolide IV, a 16-membered macrolide, have been synthesized by employing the recently developed stereospecific methylation of γ,δ-epoxy acrylates by trimethylaluminum as key steps.
Prelog-Djerassi 内酯是合成几种重要的大环内酯类抗生素的关键中间体,而原霉素 IV 是一种 16 元大环内酯,通过使用最近开发的三甲基铝对 γ,δ-环氧丙烯酸酯的立体定向甲基化作为关键合成脚步。
