针对目标化合物Obyanamide的结构特征, 运用反合成设计, 将其切为四个合成片断: N-甲基缬氨酸-N-甲基苯丙氨酸二肽(片断A)、噻唑酸衍生物(片断B)、L-乳酸衍生物(片断C)和β-氨基戊酸衍生物(片断D), 并对各个合成片断进行了合成, 最终顺利完成了对天然海洋环酯肽Obyanamide的全合成. 其化学结构经1H NMR, 13C NMR, HMBC以及HRMS (FAB)予以确证.

关键词: Obyanamide, 全合成, 天然环酯肽

Based on the structural features of obyanamide, the target molecule was disconnected into four fragments by applying retrosynthetic analysis method, i.e., N-Me-Phe-N-Me-Val (fragment A), thiazole carboxy acid derivative (fragment B), lactic acid derivative (fragment C) and unnatural 3-aminopentanoic acid (fragment D). The total synthesis of a natural marine cytotoxic cyclic depsipeptide obyanamide was accomplished successfully from synthesized the fragments A, B, C and D. The structures of the synthesized intermediates and product was identified by 1H NMR, 13C NMR, HMBC and HRMS (FAB) spectra.

Key words: total synthesis, natural cyclic depsipeptide, obyanamide
