Abstract

Partially or fully hydrogenated benzo [b] oxepines are common ring motifs found in many pharmaceutically interesting and potentially bioactive natural compounds.[1–7] Representative examples range from the structurally simple and bioactive heliannuol A,[2] pterulone,[3] and radulanin A [4] to the architecturally challenging compounds edulisoneA [5] and ovafolinin B.[6] For this reason, the establishment of new synthetic methods to ...
