2(1) helical assemblies of cinchona alkaloids in crystals: Definition of their handedness based on the molecular tilt
Cinchona alkaloids form 2, helical assemblies in their crystals. We firstly define the handedness of the assemblies on the basis of the molecular tilt. It is revealed that cinchonine and its pseudo-enantiomer, cinchonidine form 21 helical assemblies with right-and left-handedness, respectively.
