Abstract
C32H46N2O8, Mr = 586.73, m.p. 458-460 K, monoclinic, P21, a = 9.187 (2), b = 14.979 (3), c = 11.474 (2) Å, β = 104.09 (2)°, V = 1531.5 (9) Å3, Z = 2, Dx = 1.27 g cm-1, λ(Cu Kα) = 1.5418 Å, μ = 7.1 cm-1, F(000) = 632, room temperature, R = 0.039, wR = 0.053 for 3077 observed reflections [I > 3σ(I)]. The aminoethyl C(21) atom is disordered. There is an intramolecular hydrogen bond between O(3)- H(OI) and N(l) atoms, and between 0(3)- H(03) and 0(4), stabilizing the boat conformations adopted by the rings A and D.
