An efficient access to aspermytin A and oblongolide C through an intramolecular nitrile oxide-alkene [3+2] cycloaddition

Abstract

The second generation synthesis of (+)-aspermytin A and the first total synthesis of (-)-oblongolide C have been accomplished employing an intramolecular nitrile oxide-alkene [3+2] cycloaddition as the key step. © Georg Thieme Verlag Stuttgart · New York.
