Benzoxepin
Introduction '''Benzoxepin''' is an oxygen-containing bicyclic molecule consisting of an oxepin ring and a benzene ring. There are three isomers, varying in where the oxygen is positioned in the oxepin heterocycle relative where the benzene is fused to it.
Natural occurrence 1-Benzoxepin, with the oxygen closest to the benzene, is found in the skeleton of several fungal metabolites.2-Benzoxepin skeletons are likewise found in fungal metabolites.Structural formulas of perilloxin, tenual und tenucarb3-Benzoxepin, with the oxygen furthest from the benzene, is the core of natural products such as perilloxin from ''Perilla frutescens'' (variant Acuta) and tenual and tenucarb from ''Asphodeline tenuior''.
