Figure 2
The molecular structure of (II), showing the atom-numbering scheme. Displacement ellipsoids are drawn at the 30% probability level and H atoms are drawn as small spheres of arbitrary size. The absolute configurations at atoms C3 (C3′) and C16 (C16′) are both R, with the H atom of C3 pointing above the sulfonamide mean plane, as for the equivalent H atom of (I). |
