Research Abstract |
Olefin metathesis is a powerful synthetic tool in modern organic chemistry. Recently, new methods have been developed by combining several metathesis steps into a domino process. In this study, we developed the ring-opening/ring-closing metathesis of cyclobutenecarboxylate derivatives as a novel method for concise access to gamma-butenolides. Furthermore, we achieved the asymmetric total synthesis of the bioactive natural products clavilactones by use of this method.
