(6), N-(17-linolenoyloxy-linoleoyl)-glutamine (7), N-(17-linoleoyloxy-linolenoyl)-glutamine (8), and N-(17-linoleoyloxy-linoleoyl)-glutamine (9) were identified as novel surfactants in the oral secretion of several lepidopteran larvae (S. exigua, S. littoralis, S. frugiperda, and H. virescens) by LC-MS/MS and chemical degradation. Authentic reference compounds were synthesized via a dissymmetric bis-Wittig
N-(17-酰氧基-酰基)-谷氨酰胺偶联物,例如N-(17-亚麻酸-亚麻酸)-谷氨酰胺(6),N-(17-亚麻酸-亚麻酸)-谷氨酰胺(7),N-(17-亚麻酸-酰氧基) -亚油酰基)-谷氨酰胺(8)和N-(17-亚油酰氧基-亚油酰基)-谷氨酰胺(9)被确定为几种鳞翅目幼虫(S. exigua,S. littoralis,S. frugiperda,和H. virescens)通过LC-MS / MS和化学降解。真实的参考化合物是通过不对称bis-Wittig方法合成的,并确定了指定的结构。
