| Popis: | A novel concept has been established for making hetero-disubstituted cyclodextrin derivatives. Upon treatment with imidazole, 6A,6B-mesitylenedisulfonyl-capped β-cyclodextrin 1 demonstrated a reactivity about 10 times higher at the 6B position than at the 6A position, leading to the selective formation of hetero-disubstituted cyclodextrins 3. |
