Figure 6

The crystal and molecular structures of diplopterol (2) and 3-oxo-21-enedeoxyhopane (11). (A) Displacement ellipsoid plot of 2 showing the stereochemistry, with the ADPs shown at 30% probability and the hydrogen atoms shown with arbitrary radius. The second molecule is numbered as the first with 50 added to the serial number. (B) Packing diagram of 2 showing the O-H…O hydrogen-bonded chains (hydrogen atoms bound to carbon omitted for clarity). Hydrogen bond distances are as follows: O31-H311…O81: 2.756(3) Å; O81-H811…O92: 2.765(3) Å; O92-H921…O31: 2.722(3) Å. (C) Asymmetric unit for 2 with ADPs drawn at 50% probability showing the hydrogen bonds as dotted lines. (D) Displacement ellipsoid plot of 11 showing the asymmetric unit and stereochemistry, with the ADPs shown at 30% probability and the hydrogen atoms shown with arbitrary radius. (E) Packing diagram of 11 showing the weak C-H…O interactions as a dotted line. C-H…O distances are C17-H171…O3: 3.569(3) Å and C26-H261…O3: 3.419(3) Å.
