The first synthesis of triacontan-11-ol, a new fatty alcohol isolated from Argemone mexicana, has been realized starting from the nitroaldol reaction of 1-nitroicosane with decanal. Dehydration of the obtained nitroalkanol gives a long-chain nitroalkene which is then reduced to the corresponding nitroalkane. Nef transformation of the latter produces a ketone that is easily reduced to the fatty alcohol 9 in 21% overall yield.
从1-硝基二十一烷与癸醛的硝醛缩合反应出发,实现了三癸基-11-醇(一种从蓟�one mexicana中分离得到的新脂肪醇)的首次合成。所得硝基醇通过脱水反应生成一种长链硝基烯烃,随后将其还原为相应的硝基烷烃。最后,通过Nef转化得到酮,该酮易于还原为脂肪醇9,总收率为21%。
