Md. Groaning et Vt. Dsouza, ACCELERATED TRANSACYLATION OF UNACTIVATED PHENYL-ESTERS AT PHYSIOLOGICAL PH WITH BETA-CYCLOALTRAMINE, Supramolecular chemistry, 8(1), 1996, pp. 5-8
The recently reported novel cyclodextrin, beta-cycloaltramine, exhibit
s a 5.3 x 10(4) fold acceleration (compared to buffer) in transacylati
on of unactivated phenyl esters at physiological pH and follows satura
tion kinetics similar to enzymes. This acceleration is attributed to t
he change of the nucleophile and better binding of the substrate by th
is novel flexible host.
