Abstract :
Regioselective syntheses of differently functionalized cyclodextrins (CDs) were efficiently carried out under ultrasound or microwave irradiation. 6I-Deoxy-6I-thio-β-CD, 6I-deoxy-6I-formyl-β-CD, and 6A,6D-dideoxy-6A,6D-dithio-β-CD were prepared under microwave irradiation. A new rapid and efficient ultrasound-assisted protocol is described for the synthesis of 3I-azido-3I-deoxy-α, -β, and -γ-CD by selective tosylation followed by azide substitution.
