Abstract

C32H46N2O8, Mr = 586.73, m.p. 458-460 K, monoclinic, P2(1), a = 9.187 (2), b = 14.979 (3), c = 11.474 (2) A, beta = 104.09 (2) degrees, V = 1531.5 (9) A3, Z = 2, D chi = 1.27 g cm-3, lambda(Cu K alpha) = 1.5418 A, mu = 7.1 cm-1, F(000) = 632, room temperature, R = 0.039, wR = 0.053 for 3077 observed reflections [I greater than 3 sigma(I)]. The aminoethyl C(21) atom is disordered. There is an intramolecular hydrogen bond between O(1)--H(O1) and N(1) atoms, and between O(3)--H(O3) and O(4), stabilizing the boat conformations adopted by the rings A and D.
