Abstract

A complete x-ray structural investigation has been made of the alkaloid anhydroperforine. The crystals are rhombic: a=17.425(5) Å, b=8.166 Å, c=11.284(5) Å, z=4, space group P212121 (diffractometer, 1000 reflections, MLS in the anisotropic approximation, R=0.11). The investigation has unambiguously demonstrated the conformation of the anhydroperforine molecule and has confirmed its structure. The lengths of the bonds and the values of the valence angles are the usual ones. The conformations of rings B and C are planar, ring D has a chair, and ring A, a distorted half-chair conformation.
