(Azido)ynamides were efficiently converted into indoloquinolines by the use of a gold catalyst. While ynamides bearing an allylsilane gave terminal alkenes, ynamides bearing a simple alkene gave cyclopropanes. This reaction proceeds through the formation of an alpha-amidino gold carbenoid.
通过使用金催化剂,(叠氮)亚胺成功地高效转化为吲哚喹啉。其中,带有烯丙基硅烷的亚胺生成终端烯烃,而带有简单烯烃的亚胺则生成环丙烷。该反应通过形成α-胺基-金卡宾来实现。
