Abstract
- A silver‐catalyzed cycloaromatization of 1‐(2‐ethynyl‐phenyl)‐prop‐2‐yn‐1‐ol with isocyanides efficiently provides benzo[b]fluorene and benzofuran‐pyrrole derivatives through a modular cascade reaction that includes a nucleophilic attack on the diyne substrate. A C−C cross‐coupling/oxygen transportation/Diels‐Alder/hydrogen shift/isomerization cascade mechanistic pathway is proposed. [ABSTRACT FROM AUTHOR]
