  Gentrymine B, an N -Quaternary Ancistrocladus Alkaloid: Stereoanalysis, Synthesis, and Biomimetic Formation from Gentrymine A 1

  摘要：

  The total synthesis of the N-quaternary isoquinoline alkaloid gentrymine B (1) and of its unnatural enantiomer as well as its oxidative degradation is described. A further proof of stereostructure and hints at the biosynthetic origin of the unusual S,S-configuration in gentrymine B (1) were obtained by an additional biomimetic synthesis of 1 from the related-but 1R-configured-natural product gentrymine A (2), by N-methylation and subsequent spontaneous epimerization at C-l.

  Cyclombandakamines A1 (1) and A2 (2), both with an unprecedented pyrane–cyclohexenone–dihydrofuran sequence and six stereocenters and two chiral axes, are the first oxygen-bridged dimeric naphthylisoquinoline alkaloids. They were isolated from the leaves of an as yet unidentified Congolese Ancistrocladus species. Their stereostructures were established by spectroscopic, chemical, and chiroptical methods

  Cyclombandakamines A 1（1）和A 2（2）都是氧桥联的二聚萘基异喹啉生物碱，它们具有前所未有的吡喃-环己烯酮-二氢呋喃序列，并具有六个立体中心和两个手性轴。它们是从尚未鉴定的刚果Ancistrocladus物种的叶子中分离出来的。它们的立体结构是通过光谱，化学和按摩方法结合DFT和TDDFT计算而建立的。它们显然源自“开链”萘基异喹啉二聚体的一系列氧化环化反应，并表现出显着的抗原生动物活性。
