A new palladium(0)-catalyzed three-component reaction involving a set of salicylic aldehyde triflates, ethylene glycol vinyl ether, and various secondary nucleophilic amines has been developed. Through systematic optimization experiments using multivariate design, the conditions effecting robust and convenient one-pot generation of protected 3-aminoindan-1-ones were identified. A reaction route involving
已经开发了一种新的钯(0)催化的三组分反应,该反应涉及一组水杨醛三氟甲磺酸酯,乙二醇乙烯基醚和各种仲亲核胺。通过使用多变量设计的系统优化实验,确定了影响一锅生成受保护的3-氨基茚满-1-酮的条件。涉及到涉及羟烷基乙烯基醚的初始内部Heck芳基化,亚胺基离子形成和随后的串联环化反应的反应路线,以解释分离的3-氨基茚满三级缩醛的选择性形成。微波加热10-20分钟后,正交保护的3-氨基茚满1-1的氢解反应会生成伯胺或仲胺。
