The structures of ten of these, bellendine (1), isobellendine (2), darlingine (3),5,11-dihydroisobellendine (5), 2,3-dihydrobellendine (6), 2,3-epidihydrobellendine (7), 2,3-dihydrodarlingine(8), 3α-acetoxy-6β-isobutoxytropane (9), 6β-acetoxy-3α-isobutoxytropane (10) and 3α-acetoxy-6β-hydroxytropane (11), have been established.
