synthesized an advanced synthetic intermediate, hydroxy lactam 3, which has previously been converted to perhydrohistrionicotoxin. An important feature of this synthesis is the creation of stereogenic centers by using the cyclic amino acid ester−enolate Claisen rearrangement together with a ring-closing metathesis for azaspirocyclic skeleton construction.
