The pentadecyl 6-hydroxydodecanoate 8, a new hydroxy ester isolated from leaves of Artabotrys odoratissima has been synthesized, for the first time, from α-nitrocyclohexanone 1, via (i) nucleophilic ring cleavage performed with 1-pentadecanol 2, (ii) nitroaldol reaction of the formed ω-nitro ester 3 with hexanal 4, (iii) dehydratation of the obtained nitroalkanol 5 to the conjugate ni-troolefin 6,
6-羟基十二烷酸十五烷基酯 8 是一种从青蒿叶中分离的新羟基酯,首次由 α-硝基环己酮 1 合成,通过 (i) 用 1-十五烷醇 2 进行的亲核环裂解,(ii) 硝基醛醇形成的 ω-硝基酯 3 与己醛 4 的反应,(iii) 获得的硝基烷醇 5 脱水为共轭硝基烯烃 6,(iv) 硝基烯烃 6 直接 Nef 转化为酮酯 7,和 (v)硼氢化钠还原羰基官能团,以将酮酯 7 转化为目标羟基酯 8。
