A Versatile Approach toward the Ansamycin Antibiotics

The ansamycin antibiotics contain metacyclophanic macrolactams, many of which possess potent antitumor activity. Only a few total syntheses of this family of natural products have been reported, and modifications to increase potency have not been described. Therefore, a method was developed to prepare the trienomycin A core via resin-bound triphenylphosphonium salts, which serve as both a reagent and a traceless linker to afford olefinic products that undergo ring-closing metathesis (RCM) to give macrocyclic scaffolds of varying ring sizes.

an asymmetric total synthesis of (+)-duocarmycin SA. Further extensions of the studies provided key yatakemycin partial structures and analogues for comparative assessments. This included the definition of the DNA selectivity (adenine central to a five-base-pair AT sequence, e.g., 5'-AAAAA), efficiency, relative rate, and reversibility of ent-(-)-yatakemycin and its comparison with the natural enantiomer
对提供第一次矢车菊霉素全合成导致其结构修正和绝对立体化学分配的研究的补充,本文公开了第二代不对称全合成。由于单独的 yatakemycin 亚基与 duocarmycin SA(烷基化亚基)或 CC-1065(中央和右侧亚基)的亚基相同,因此这些研究还改进了我们早期的 CC-1065 全合成,如本文所详述,已扩展到 (+)-duocarmycin SA 的不对称全合成。研究的进一步扩展为比较评估提供了关键的 yatakemycin 部分结构和类似物。这包括 DNA 选择性(五碱基对 AT 序列的中心腺嘌呤,例如 5'-AAAAA)、效率、相对速率、ent-(-)-yatakemycin 的可逆性及其与天然对映异构体的比较(相同的选择性和效率),腺嘌呤 N3 加合物的结构表征证实了 DNA 反应的性质,以及天然产物的细胞毒活性的比较( L1210, IC50 = 5 pM) 及其非天然对映异构体
