Anwendungen

Tetrabenzyl pyrophosphate is used in the preparation of phosphoryl derivatives of shikimic acid in the presence of LDA. It is used in the preparation of dibenzyl phosphoro fluoridate in the presence of cesium fluoride as a catalyst. It is also used as a precursor in pharmaceuticals and involved in the phosphorylation of inositol derivatives.

Bemerkungen

Moisture sensitive. Incompatible with strong oxidizing agents, strong acid and bases and reducing agents.

Useful reagent for O-phosphorylation. Used in preparation of phosphoryl derivatives of shikimic acid, by reaction in the presence of LDA; subsequent debenzylation was accomplished with TMS bromide: J. Org. Chem, 51, 75 (1986). Used to phosphorylate inositol derivatives in the presence of KH or NaH in THF: J. Am. Chem. Soc., 109, 3478 (1987); J. Chem. Soc., Chem. Commun., 298 (1991); the required debenzylated products were obtained by catalytic hydrogenolysis.
