A tandem Wittig approach has been employed for the synthesis of both (11S,9Z,12Z,15Z)- and (11R,9Z,12Z,15Z)-hydroxyoctadeca-9,12,15-trienoic acid (11-hydroxylinolenic acid, 11-HLA) from (R)-glyceraldehyde acetonide. From (11R)-HLA we have prepared the corresponding palmitic acid and stearic acid esters, mayolene-16 (1) and mayolene-18 (2), insect defensive compounds recently identified from Pieris rapae larvae. In addition, we describe the synthesis of three macrocyclic oligomers (24-26) derived from (11R)-HLA.
已采用串联维蒂希方法从(R)-甘油醛丙酮化物合成(11S,9Z,12Z,15Z)-和(11R,9Z,12Z,15Z)-羟基十八碳-9,12,15-三烯酸(11-羟基亚麻酸,11-HLA)。从(11R)-HLA我们制备了相应的棕榈酸酯和硬脂酸酯,即mayolene-16(1)和mayolene-18(2),它们是最近从菜粉蝶幼虫中鉴定出的昆虫防御化合物。此外,我们描述了由(11R)-HLA衍生的三种大环低聚物(24-26)的合成。
