  摘要：

  环三肽 X-13 是一种从红树林真菌 Xylaria sp.（编号 2508）中分离出来的新型海洋化合物 xyloallenoide A 的核心成分。我们发现，X-13 可剂量依赖性地诱导斑马鱼胚胎和人类内皮细胞的血管生成，同时增加 eNOS 和 Akt 的磷酸化以及 NO 的释放。用 LY294002 或 l-NAME 抑制 PI3K/Akt/eNOS 可抑制 X-13 诱导的血管生成。本研究表明，X-13通过PI3K/Akt/eNOS途径促进血管生成。

  A unified catalytic asymmetric (N+1) (N=4, 5) annulation reaction of oxindoles with bifunctional peroxides has been achieved in the presence of a chiral phase-transfer catalyst (PTC). This general strategy utilizes peroxides as unique bielectrophilic four- or five-atom synthons to participate in the C−C and the subsequent umpolung C−O bond-forming reactions with one-carbon unit nucleophiles, thus providing
