Aj. Kirby et R. Stromberg, INTRAMOLECULAR NUCLEOPHILIC CATALYSIS OF GLUCOSIDE HYDROLYSIS BY THE 2-PHOSPHATE GROUP, Journal of the Chemical Society, Chemical Communications, (6), 1994, pp. 709-710
4-Nitrophenyl beta-D-glucoside tetraphosphate is hydrolysed 100 times
faster than the 2-methoxy derivative, by way of the 1,2-cyclic phospha
te diester, which is solvolysed by attack at phosphorus.
