The synthesis of functionalized cyclodextrins as scaffolds and templates for molecular diversity, catalysis, and inclusion phenomena

α-, β-, and γ-cyclodextrins were chemically modified to selectively introduce functionality on the primary and secondary faces. Azido and substituted alkenyl groups were selectively introduced on the primary hydroxy groups to give monosubstituted derivatives. The secondary C-2 hydroxy group was selectively functionalized with allyl, 1-hexenyl, carboxymethyl, and ω-azidoalkyl groups (n: 3, 4, 5) as ethers. The chemically modified cyclodextrins are versatile molecules for use as scaffolds and templates in conjunction with chemical diversity, catalysis, and inclusion phenomena.
