Figure 1
The structure of one of the two independent molecules in (I), with displacement ellipsoids at the 20% probability level. The minor component of the disorder for the substituents at C23 has been omitted (i.e. O22, H22 and H232), so that the Cα-S major isomer in the solid state is shown. For clarity, H atoms, except H21 and H231, have been omitted. |
