Recent advances in the synthesis of cyclodextrin derivatives under microwaves and power ultrasound.

Abstract  We describe improved syntheses of CD derivatives, like 6^I-monotosyl, 6^I-monoazido-6^I-monodeoxy, 6^I-monoamino-6^I-monodeoxy-βCD and 2^I-O-mono(methylamino)alkyl-βCDs, that were carried out under US or MW, to great advantage in terms of yield, purity and reaction time. In the search for more efficient procedures to prepare monosubstituted CDs, we applied MW and/or US to some fundamental preparations such as those of 6^I-amino-6^I-deoxy-βCD and a series of 2-monoaminomethyl-βCD derivatives.
