Abstract
A new synthetic protocol that combines the advantages offered by eco-friendly solvent-free reactions and sequential transformations is reported. This strategy offers straightforward access to benzo[c]chromenes and benzo[b]furans from commercially available starting materials. This two-step, one-pot strategy consists of an Au-catalyzed hydrophenoxylation process followed by Pd-catalyzed C-H activation or Mizoroki-Heck reactions. The selectivity of the process towards C-H activation or Mizoroki-Heck reaction can be easily tuned.
