    • -3. Due to a large standard deviation the result of an attempted determination of the absolute configuration using Flack's method32 turned out to be insignificant. However, based on chemical evidence the chirality of the molecule could be assigned as shown in Figure 1. The hydroxyl hydrogen atoms could be located and have been refined isotropically. Most of the other hydrogen positions have been calculated in idealized positions, and their Us have been fixed at 1.5 times U of the relevant heavy atom without refinement of any parameters. The crystal structure of 4c has been deposited as supplementary publication no. CCDC 268224 at the Cambridge Crystallographic Data Centre.
