4-Bromo-1-butene has been used in a preparation of dienehydrazides which, in turn, provided cyclic enehydrazides by ring closing metathesis. Double alkylation of lactams, followed by Grubbs ring-closing metathesis, gives access to the bicyclic spiroimine ring system of the bicyclic spiroimine ring system of the biotoxin gymnodimine.
