• Reagent for the introduction, in the presence of a base such as triethylamine or imidazole in DMF, of the thexyldimethylsilyl (TDS) group for protection of hydroxyl functions. The greater steric hindrance of the TDS group compared with TBDMS confers greater (at least 2-3x) stability to acid or base hydrolysis. Cleavage with F^- is also about 2-3x slower than for TBDMS: Tetrahedron Lett., 26, 5511 (1985); 32, 2135 (1991). TDS is also an extremely useful protecting group for nitrogen functions, providing readily purifiable derivatives which survive a variety of chemical transformations, but are readily cleaved by F^-: Tetrahedron Lett., 26, 5515 (1985); J. Chem. Soc., Perkin 1, 423 (1998).
