An improved second-generation synthesis of the unnatural amino acid components of the anticancer peptaibol culicinin D has been developed. With a protected glutamic acid derivate as the starting material, the process readily delivered the Fmoc-protected free acid derivatives of AHMOD ((2S)-amino-(6R)-hydroxy-(4S)-methyl-8-oxodecanoic acid) and AMD ((2S)-amino-(4S)-methyldecanoic acid) required to support
已开发出抗癌肽醇culicinin D的非天然氨基酸成分的改进的第二代合成方法。以受保护的谷氨酸衍生物为起始原料,该方法可以轻松递送AHMOD((2 S)-氨基-(6 R)-羟基-(4 S)-甲基-8-氧代十二烷酸)的Fmoc保护的游离酸衍生物)和AMD((2 S)-氨基-(4 S)-甲基癸酸)支持固相肽合成(SPPS),用于天然产物的结构活性研究。相同的方法还提供了改善的胡椒酸衍生物的途径。还报道了在这项工作中开发的一种新型的Wittig试剂,用于醛的一碳均化。
