| 中文摘要 | A 6,(17)-epoxylathyrolditerpenoid((2S*3S*4R*5R*6S*9S*11S*15R*)-5,15-diacet oxy-3-phenylacetoxy-14-oxolathyra-6(17),(12E)-diene-6(17)-epoxide) was isolated from the seeds of Euhporbia lathyris L. Its configuration was puzzled because of the incomplete X-ray results reported before. In this work, the atom connectivity and configuration were confirmed by single-crystal X-ray diffraction together with ESI-MS, H-1-, and C-13-NMR spectroscopy. The compound crystallizes in monoclinic, space group P2(1) with a = 11.386(1), b = 8.2839(7), c = 17.192(2) angstrom, beta = 108.305(2)degrees, Z = 2, V = 1539.5(2) angstrom(3), C32H40O8, M-r = 552.64, D-c = 1.192 g/m(3), F(000) = 592, mu(MoK alpha) = 0.085 mm(-1), T = 293(2) K, the final R = 0.0398 and wR = 0.0950 for 2057 observed reflections with I > 2 sigma(I). The molecule shows a tricyclic terpenoid skeleton, consisting of fused five-, eleven- and three-membered rings. The configuration at C(5) is R* and that at C(6) S*. |
