Referencias documentales

Reagent for protection of alcohols, cf Chlorotriphenyl­methane, A11799, as their monomethoxytrityl (Mmt) ethers, intermediate in acid-lability between trityl (Trt) and dimethoxytrityl (Dmt); see 4,4'-Dimethoxytrityl­ chloride, A11626. For use of DMAP as a catalyst for methoxytritylation of alcohols and amines, see: Tetrahedron Lett., 21, 3899 (1980); J. Org. Chem., 47, 571 (1982); Chem. Lett., 15 (1982).

In a comparison with Dmt for N-protection during solid-phase peptide synthesis, the N-Mmt group was found to survive intact whereas N-Dmt derivatives decomposed slowly in protic solvents: Tetrahedron. Lett., 39, 1733 (1998).
