The antifungal, naturally occurring acetylenic fatty acid 6‐nonadecynoic acid was synthesized in three steps (18 % overall yield), for the first time starting with commercially available 1‐tetradecyne. The synthesis developed herein will facilitate the further study of the antifungal properties of this naturally occurring acetylenic fatty acid. The 6‐nonadecynoic acid exhibited the best antifungal activity
抗真菌的天然存在的炔属脂肪酸 6-壬酸是通过三步合成的(总产率为 18%),这是第一次从市售的 1-十四炔开始。开发的合成将有助于进一步研究这种天然存在的炔属脂肪酸的抗真菌特性。在 Sabouraud 葡萄糖肉汤 (SDB) 培养基中,6-壬酸对新型隐球菌 ATCC 66031 表现出最佳的抗真菌活性 (<4.3 μM)。在我们手中,它对白色念珠菌 ATCC 14053 和白色念珠菌 ATCC 60193 没有活性。
