(±)-Vertinolide (1) was synthesized from the readily available tetronic acid derivative 5 in 3 steps. The Michael reaction of the anion derived from 6 with (E)-5-ethoxyocta-1,6-dien-3-one (12) gave the vertinolide precursor 9 in high yield, which was then easily converted to (±)-vertinolide (1).
(±)-Vertinolide (1) 由容易获得的特窗酸衍生物 5 分 3 个步骤合成。衍生自 6 的阴离子与 (E)-5-乙氧基辛基-1,6-二烯-3-酮 (12) 发生迈克尔反应,以高产率得到维替内酯前体 9,然后很容易将其转化为 (±)-维替内酯(1).
