A gold-catalyzed tandem intramolecular hydroaminationâformal aza-DielsâAlder reaction of propargylic amino esters is described. The overall process leads to the formation of a tetracyclic framework as a single diastereoisomer, with the creation of four bonds and five stereocenters.
该研究描述了一种
金催化的分子内串联氢化-形式氮杂-DielsâAlder 反应。整个反应过程形成了四环框架的单非对映异构体,并生成了四个键和五个立体中心。
