The first total syntheses of (+)-alismoxide and (+)-4-epi-alismoxide are reported. Formal chemo-, regio-, and stereoselective addition of water to 10α-acetoxy-1αH,5βH-guaia-3,6-diene afforded the target compounds after reduction. The absolute stereochemistry of (+)-alismoxide has been established. The low [α]D +8.6 value indicates that significant amounts of alismoxide result from biosynthetic processes
4- -的第一全合成(+) - alismoxide和(+)外延报告alismoxide。正式化疗选择性,区域选择性,立体选择性和添加水到10α乙酰氧基1α ħ,5β ħ -guaia -3,6-二烯还原后得到目标化合物。(+)-alismoxide的绝对立体化学已经建立。[α] D +8.6的低值表示生物合成过程中产生大量的Alismoxide。此外,天然guaienediol的分离自结构串叶松香草已被校正到( - ) - alismoxide。
