and 13-step routes using 2-chlorophenol and 4-chlorophenyl methyl ether as the starting materials in overall yields of 2.7% and 12%, respectively. Their structures were characterized by 1H and 13C NMR, HRESIMS, and X-ray diffraction data. The structure of palmarumycin B6 was revised as 6-chloropalmarumycin CP17. The bioassay results showed that the larvicidal activity of palmarumycin B6 with an LC50 value
以2-氯苯酚和4-氯苯基甲基醚为起始原料,通过7和13步路线合成了棕榈古霉素B 6及其区域异构体,总收率分别为2.7%和12%。它们的结构通过1 H和13 C NMR,HRESIMS和X射线衍射数据表征。棕榈铝霉素B 6的结构被修改为6-氯palumumycin CP 17。生物测定结果表明,LC 50值为32.7μM的棕榈金霉素B 6的杀幼虫活性显着高于其8氯异构体的LC 50值为227.3μM的杀幼虫活性。
