involves a ring-closingring-opening sequence providing a new and straightforward access to an interesting class of heterocyclic compounds. Furthermore, starting from pyroglutamates allows the synthesis of highly substituted hydantoins under very mild conditions. This ring transformation in combination with ring-closingmetathesis is used in a four-step reaction sequence for the synthesis of multi-functionalised
