the azaanthraquinone skeleton from N-propargylamino quinone by a Au(I)-catalyzed 6-endo-dig cycloisomerization was developed. The catalytic process was applied to the synthesis of alkaloid cleistopholine and its analogues. A mechanism involving benign nucleophilicity of the aminoquinone was proposed.
开发了一种通过Au(I)催化的6- endo - dig环异构化从N-炔丙基氨基醌组装氮杂蒽醌骨架的方法。该催化过程被应用于生物碱抗胆碱及其类似物的合成。提出了涉及氨基醌良性亲核性的机理。
