  Synthesis of Polycyclic Aromatics and Heteroaromatics via Electrophilic Cyclization

  摘要：

  A variety of substituted polycyclic aromatics are readily prepared in good to excellent yields under very mild reaction conditions by the reaction of 2-(1-alkynyl)biphenyls with ICl, I-2, NBS, and p-O2NC6H4SCl. This methodology readily accommodates various functional groups and has been successfully extended to systems containing a variety of polycyclic and heterocyclic rings.

  The first report of 1,2-dicarbofunctionalization of alkynes using organohalides as coupling partners in the field of gold catalysis has been presented. Mechanistic investigations, including NMR, tandem mass spectrometry and DFT studies, reveal that an oxidative addition/carbophilic activation pathway is preferred over the migratory insertion/cis-trans isomerization pathway.
