The domino effect: A novel, cationic, gold(I)‐catalyzed [3+2], tandem bicyclization, which provides rapid, efficient, and diastereoselective access to highly substituted cyclopenta[c]furans from simple, readily available 2‐(1‐alkynyl)‐2‐alken‐1‐ones and 3‐styrylindoles under mild conditions, is described (see scheme).
多米诺效应:一种新颖的,阳离子的,金(I)催化的[3 + 2],串联bicyclization,它提供了高度取代的环戊二烯并[快速,高效,非对映选择性访问Ç从简单]呋喃,容易获得的2-(1-描述了在温和条件下的(炔基)-2-烯键-1-酮和3-苯乙烯基吲哚(参见方案)。
