(–)-exo-Isobrevicomin (1S,5R,7S)-(–)-5-ethyl-7-methyl-6,8-dioxabicyclo[3.2.1]octane (1)} and its (–)-endo isomer [(1S,5R,7R)-2] were synthesized by employing the acetylenic acetal 7 as the common intermediate and by using the Sharpless asymmetric dihydroxylation and lipase-catalyzed acetylation as the key reactions.
(–)- exo -Isobrevicomin (1 S,5 R,7 S)-(–)-5-乙基-7-甲基-6,8-二氧杂双环[3.2.1]辛烷(1)}及其(– )-内异构体[(1 S,5 R,7 R)-2 ]是通过使用乙炔缩醛7作为常见中间体并以Sharpless不对称二羟基化和脂肪酶催化的乙酰化为关键反应合成的。
