Abstract: A new and effective method for making bridged bicyclic benzoxepine derivatives were devised through the intermolecular [3+3]‐annulation of benzoxepine‐3‐carboxylates with aminocrotonates in the presence of La(OTf)3. The compounds were formed through reactions involving the benzoxepine… read more here.
