DESCRIPTION (provided by applicant): The objective of the proposed research is to develop an enantioselective total synthesis of diazonamide A. The natural product was isolated from the marine ascidian diazona chinensis, and possesses potent in vitro activity against HCT-116 human colon carcinoma and B-16 murine melanoma cancer cell lines with IC50 in the nanomolar range. The proposed research utilizes a novel organocatalysis strategy, developed in the MacMillan group, to generate the furolindoline core of diazonamide. Successful installation of the furolindoline core will serve as the platform for refining and developing new chemical methods to complete the bismacrocyclic framework of diazonamide A. An expeditious completion of the natural product will not only provide a synthetic sample, but also permits access to unnatural analogues for further biological evaluation.

描述（由申请人提供）： 本研究的目的是开发重氮酰胺A的对映选择性全合成方法。该天然产物是从海洋海鞘重氮酰胺A中分离出来的，对HCT-116人结肠癌和B-16鼠黑色素瘤癌细胞具有有效的体外活性IC50 在纳摩尔范围内。拟议的研究利用麦克米伦小组开发的新型有机催化策略来生成重氮酰胺的呋喃并啉核心。呋喃并啉核心的成功安装将作为精炼和开发新化学方法的平台，以完成重氮酰胺A的双大环骨架。天然产物的快速完成不仅将提供合成样品，而且还允许获得非天然类似物进一步的生物学评价。
