An optically pure C-6 O-acyl side chain equivalent of zaragozic acid A, (2E, 4S, 6S)-4, 6-dimethyl-2-octenoic acid, which features a 1, 3-syn-dimethyl-substituted carbon chain, has been readily synthesized from (S)-2-methylbutanal using a combination of the Evans aldol reaction and the Ireland deoxygenation method.
利用埃文斯醛醇反应和爱尔兰脱氧法的结合,从 (S)-2- 甲基丁醛轻松合成了光学纯度为 C-6 O-酰基侧链等价物的萨拉戈萨酸 A,即 (2E,4S,6S)-4,6-二甲基-2-辛烯酸,它具有 1,3-炔二甲基取代的碳链。
