《Crystal Studies and Antitumor Activities of Novel D-seco-taxoids Derived from 1-Deoxybaccatin Ⅵ》
The suitable colorless single crystals of the title compounds were obtained by slow diffusion in EtOAc and petroleum ether.A summary of the crystallographic information is given in Table 1.The selected bond distances and bond angles are listed in Table 2.The selected crystal was mounted on an ENRAF-NONIUS CAD4 diffractometer.Diffraction data were measured at 293(2)K using graphitemonochromatic Mo Kα(λ=0.071073 nm)radiation.The structure was solved by direct methods using SHELXS-97,and refined by full-matrix least-squares on F2,SHELXL-97.All non-hydrogen atoms were refined anisotropically,and all hydrogen atoms were placed in calculated positions and refined with a'rider'scheme allowing for the rotation of methyl(AFIX 137)and hydroxyl(AFIX 147)groups.It should be noted that there are two pores,338?3,in the unit cell of compound 3 which are caused by solvent molecules.
