arrests cells in the G2/M phase of mitosis similar to paclitaxel, and its bioactivity was comparable to that of peloruside A. NMR-directed isolation, structure elucidation, structure confirmation by totalsynthesis, and bioactivity of peloruside B are described in this article. The synthesis features Sharpless dihydroxylation, Brown’s asymmetric allylboration reaction, reductive aldol coupling, Yamaguchi
Peloruside B ( 2 ) 是 peloruside A ( 1 )的天然同源物,是从新西兰海洋海绵Mycale hentscheli 中以亚毫克量分离的。Peloruside B与紫杉醇类似,促进微管聚合并在有丝分裂的 G 2 /M 期阻滞细胞,其生物活性与 peloruside A 相当。 核磁共振定向分离、结构解析、全合成结构确认和 peloruside 的生物活性B 在这篇文章中有描述。合成的特点是 Sharpless 二羟基化、布朗的不对称烯丙基硼化反应、还原醛醇偶联、山口大环内酯化和选择性甲基化。
