## Abstract Hexakis(2,3‐di‐__O__‐methyl)‐α‐cyclodextrin was treated with 2,4‐dimethoxybenzene‐1,5‐disulfonyl chloride to give 6^A^,6^B^‐di‐__O__‐sulfonated product 5 in only a 3.0% yield. When treated with sodium __p__‐allyloxyphenoxide, 5 gave 6^A^,6^B^‐(bis‐__O__‐__p__‐allyloxyphenyl)hexakis(2,3‐
