cycloisomerization-initiated tandem reaction of Boc-protected indole tethered homopropargyl amides has been achieved. This method delivers a wide range of valuable bridged aza-[n.2.1] skeletons (n = 3–7) at room temperature with high diastereoselectivity and enantioselectivity by a chirality-transfer strategy. Moreover, the gold-catalyzed tandem reaction of homopropargyl alcohol is also achieved to produce
摘要实现了由Boc保护的吲哚链式均炔丙基酰胺的高效金催化抗马氏复合环引发的串联反应。该方法可通过手性转移策略在室温下提供多种有价值的桥连氮杂[n.2.1]骨架(n = 3-7),具有高非对映选择性和对映选择性。此外,还实现了金炔丙醇的串联催化反应,以生产桥联的氧杂-[3.2.1]骨架。
