The first total syntheses of five elegan-type linear diterpenes-eleganolone (1), eleganolone acetate (2), elegandiol (3), eleganonal (4), and epoxyeleganolone (5)-were accomplished starting from (E,E)-farnesol (6) via four to six steps, successively, with high overall yield. The key step was the alkylation reaction of silyl cyanide with allylic iodide.
从(E,E)-法尼醇开始完成了五种线型线性二萜烯-依兰诺酮(1),醋酸依来诺龙(2),elegandiol(3),eleganonal(4)和环氧烯醇酮(5)的第一批总合成。 (6)连续经过四到六个步骤,总收率很高。关键步骤是甲硅烷基氰化物与烯丙基碘化物的烷基化反应。
