6-Hexyl-3- [7- (methoxycarbonyl) heptyl] -1-cyclohexene-4, 5-dicarboxylic anhydride (1) obtained by the addition of maleic anhydride to methyl (E, E) -9, 11-octadecadienoate was treated with m-chloroperbenzoic acid in chloroform to give 4, 5-epoxy-6-hexyl-3- [7- (methoxycarbonyl) heptyl] -1, 2-cyclohexanedicarboxylic anhydride (2). The 1H-NMR, 13C-NMR, IR, EI-MS, and CI-MS spectroscopies of (1) and (2) indicated (1) and (2) to each have predominantly the half-chair conformation structure.
