The gold-catalyzed tandem cyclization of 1,2-bis(alkynyl)-2-en-1-ones with indoles offers an efficient and straightforward route to indole-fused polycyclic systems. The process is realized through a cascade carbonyl-yne cyclization/Friedel–Crafts/indole-yne cyclization sequence catalyzed by a single-pot catalyst of gold.
1,2-双(炔基)-2-en-1-one与吲哚的金催化串联环化为吲哚稠合的多环体系提供了一条有效而直接的途径。该过程是通过单罐金催化剂催化的羰基-炔级联/ Friedel-Crafts /吲哚-炔级联反应来实现的。
