A chiral molecular bowl containing three ferrocenes: synthesis and its efficiency in an optical resolution of 1,1'-bi-2-naphthol.

Condensation reaction of 1,1'-ferrocenedicarboxaldehyde with (1R,2R)-1,2-diaminocyclohexane affords a novel bowl-shaped macrocycle with a chiral concave cavity which exhibits a remarkable ability as a host material for the enantioselective enclathration of 1,1'-bi-2-naphthol.
