Chiral differentiation in the deacylation of 6A-O-{2-[4-(2-methylpropyl)phenyl]propanoyl}-β-cyclodextrin

Abstract
In 0.1 mol dm–3 sodium carbonate buffer at pH 11.5 the pseudo first-order rate constants for the hydrolysis of the diastereoisomers of the title compound to give Ibuprofen {2-[4-(2-methylpropyl)phenyl]propanoic acid} and β-cyclodextrin are 2.97 × 10–5 s–1 and 3.16 × 10–4 s–1, with the diastereoisomer derived from (R)-Ibuprofen being the most susceptible to hydrolysis.
