- Reagent for the protection of diols, including carbohydrate-type molecules, as their 1,3-(1,1,3,3-tetraisopropyldisiloxanylidene) (TIPDS) derivatives, formed in the presence of imidazole: J. Chem. Res. Synop., 24 (1979); J. Org. Chem., 50, 1651 (1985), or pyridine-DMF: Tetrahedron, 41, 4545, 4557 (1985). The high steric demand of the TIPDS group enables discrimination between primary and secondary OH. It is readily cleaved by F- (e.g. TBAF in THF) or by aqueous acid or base. See Appendix 4.
