## Abstract A chiral imidazolinium salt with two bulky carbohydrate subunits, __N__,__N__′‐1,3‐bis(methyl 4,6‐__O__‐benzylidene‐3‐deoxy‐α‐D‐altropyrano‐3‐yl)imidazolinium chloride (**4**), was synthesized in high yield. Deprotonation of **4** with sodium __tert__‐butoxide in the presence of [RhCl(C
