  Synthesis of the staurosporine aglycon

  摘要：

  A short synthesis of the staurosporine aglycon (6) is reported, the indolocarbazole skeleton being constructed by an intramolecular Diels-Alder reaction followed by a nitrene-mediated ring closure. The synthesis starts by acylation of ethyl indole-2-acetate with oxalyl chloride. The resulting indole-3-glyoxalyl chloride is quenched with 2-nitrocinnamylamine (29) to give the amide (31). Hydrolysis of the ester group and cyclodehydration then gives the pyranoindolone (35). On heating in bromobenzene, the pyranoindolone 35 undergoes intramolecular Diels-Alder reaction to give, after loss of carbon dioxide and air oxidation, the carbazole 36, which on treatment with triethyl phosphite cyclizes to the staurosporine aglycon. The overall yield from ethyl indole-2-acetate is 22.6%.

  An efficient methodology taking advantage of the excellent nucleophilicity of aminoquinone to assemble the azaanthraquinone framework was developed via an iodine-induced 6-endo-dig electrophilic cyclization. Therefore, starting from N-propargylaminoquinones, various 3-iodo-1-azaanthraquinones were obtained in yields ranging from 45% to 90%. The metal-free protocol features facile installation of an iodine atom on the azaanthraquinone ring and benign functional group compatibility.

  通过碘诱导的 6-endo-dig 亲电环化，开发了一种利用氨基醌优异的亲核性来组装氮杂蒽醌框架的有效方法。因此，从N-炔丙基氨基醌出发，得到了各种3-碘-1-氮杂蒽醌，产率在45%至90%之间。无金属协议的特点是在氮杂蒽醌环上易于安装碘原子以及良好的官能团兼容性。
