DETAILS

Description (English)

Application
Double alkylation of lactams, followed by Grubbs ring-closing metathesis, gives access to the bicyclic spiroimine ring system of the biotoxin gymnodimine.1
Used in a preparation of dienehydrazides which, in turn, provided cyclic enehydrazides by ring closing metathesis.
Packaging
