Highly efficient gold-catalyzed atom-economical annulation of phenols with dienes.
[reaction: see text] A highly efficient annulation of phenols and naphthols with dienes was developed by using a combination of AuCl(3)/AgOTf as catalyst. The annulation generated various benzofuran derivatives under mild conditions rapidly.
