The target compound was synthesized in two steps. 4-(Dimethylamino)benzaldehyde, 4β-amino podophyllotoxin, two drops of acetic acid in 95% ethanol was stirred for 6 h. Appropriate amount of NaBH4 was added into the reaction mixture to stirred for 1 h at 273 K. Then add 5% HCl to end off the reaction, the reaction mixture was concentrated in vacuo. Add saturated NaHCO3 to adjust PH>7. The reaction mixture was extracted with CH2Cl2 and dried over MgSO4 and concentrated in vacuo. The residue was resolved in a methanol solution and slow evaporation over two weeks at room temperature gave transparent crystals suitable for X-ray analysis.
C-bound H atoms were found on difference maps, but placed in idealized positions with C—H = 0.95–1.00 Å, and refined as riding, with Uiso(H) = 1.2Ueq(C) for aryl and methylene H atoms and 1.5Ueq(C) for the methyl H atoms. N-bound H atoms were located on a difference map and isotropically refined. In the absence of any significant anomalous scatterers in the molecule, the 2920 Friedel pairs were merged before the final refinement.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

Podophyllotoxin and its derivatives are well known as substances with anti-cancer activity. In our group, we synthesize different kinds of Podophyllotoxin compounds in the search for new derivatives with improved bioactivities (Lu et al., 2010; Yu et al., 2008; Zhao et al., 2009). In this paper, we present the crystal structure of the title compound (I).
In (I) (Fig. 1),the bond lengths and angles are normal and in a good agreement with those reported previously for related compounds (Feng et al., 2008; Zhang et al., 1994; Zuo et al., 2009). The tetrahydrofuran ring (C6—C9/O3) and the six-membered ring (C4—C6/C9—C11) fused to it both display envelope conformations. The dihedral angles between the benzene ring (C2—C4/C11—C13) of the benzo[d]-[1,3]dioxole and the other two benzene ring (C23—C88 and C15—C20) are 89.68 (3) and 63.38 (2) °, respectively.
Weak intermolecular C—H···O interactions (Table 1) stabilize the crystal packing.
