Abstract Cyclodextrins (cyclomalto-oligosaccharides, CDs) induceregioselectivecleavage of the 3′,5′-phosphodiester linkages in di- and poly-ribonucleotides at pH 11.08 and 50°. 0.15 m Cyclomaltohexaose (α-CD) mediates the cleavage of CpA, CpC, CpG, and CpU to give 96–97% of cytidine 3′-phosphate together with adenosine, cytidine, guanosine, and uridine, respectively. In the absence of α-CD, 50–52%
