M. Oivanen et al., HYDROLYSIS AND METHANOLYSIS OF THE PHENYL ESTER OF THYMIDINE 3',5'-CYCLIC-MONOPHOSPHATE - PH-DEPENDENT COMPETITION BETWEEN PO AND CO BOND RUPTURES, Collection of Czechoslovak Chemical Communications, 61, 1996, pp. 26-29
pH-Rate profiles and product distributions for the hydrolytic reaction
s of the cis-phenyl ester of thymidine 3',5'-cyclic monophosphate have
been determined over the pH-range 0-14. The pH-independent hydrolysis
(pH 2-7) of the phosphotriester moiety appears to proceed mainly by c
leavage of the C5'O bund, whereas the hydroxide- and hydronium-ion-cat
alyzed reactions involve rupture of one of the PO bonds.
