- •
Both epimeric of 4,5-secocholest-3-yn-5-ols were prepared from cholesterol.
- •
Reaction with terephthaloyl chloride led to crystalline dimeric terephthalates.
- •
The configuration at C-5 plays an important role in the crystal packing.
- •
Hydrophobic interactions promote multilayer or helicoidal self assemblies.
