Cu- and Pd-catalyzed arylation of aminocholanes has been described for the first time. While this Cu-catalyzed protocol provides high yields in reactions of aminocholanes with iodoarenes, Pd catalysis was found to be preferable for the reactions of aminocholanes with dichloroanthraquinones. UV-vis titration of bis(cholanylamino)anthraquinones with a series of cations demonstrated their high binding

Compositions are provided which contain immobilized flavorants, in the form of supramolecular complexes of flavorant compounds, for flavor delivery. One embodiment relates to the flavorant supramolecular complexes themselves; Other embodiments relate compositions which contain the flavorant supramolecular complexes and a substrate. In particular embodiments, the substrate is smokable, but in other embodiments may be non-smokable or comestible.
