Synthesis of Benzo[b]azepines via Intramolecular Cyclization of 2-Alkenyl-N-propargylanilines.
An atom-economical and catalyst-free synthesis of benzo[b]azepines is described by tuning an intramolecular cyclization of 2-alkenyl-N-propargylanilines. The reaction was presumed to proceed through an in situ formation of aza-o-quinone methide (aza-o-QM), followed by 1,6-enyne cyclization under thermal conditions. The...
