## Abstract Transferring the site of specific substitution of dipentylated cyclodextrins with methyl or acyl residues from the secondary 3‐hydroxyl group to the primary 6‐hydroxyl group was expected to provide new information on the mechanism of chiral recognition. The 3‐position points towards and
