N‐heterobicyclic scaffolds: Highlyefficient palladium‐catalyzed cyclizations of oxime esters with cyclic alkenes were used as a general entry to perhydroindole and related scaffolds. The chemistry is reliant upon the use of P(3,5‐(CF3)2C6H3)3 for the key C(sp3)N bond‐forming process and this facilitates cyclizations with enhanced levels of efficiency across a range of sterically and electronically
N-杂环双环支架:肟酯与环烯烃的高效钯催化环化反应通常用作过氢吲哚和相关支架的入口。化学过程依赖于关键的C(sp 3)N键形成过程使用P(3,5-(CF 3)2 C 6 H 3)3的形成,这有利于环化反应,并提高了整个反应过程的效率。一系列在空间和电子方面不同的基材。
