Reagent for protection of the carboxyl group as its 2-(p-toluenesulfonyl)ethyl (Tse) [2-(4-methylphenylsulfonyl)ethyl (Mpse)] ester, e.g. by DCC coupling. The Tse group is useful for carboxyl protection of Boc amino acids in peptide synthesis, since it is stable to the acidic conditions used for Boc cleavage, but readily cleaved by mild base, e.g. dilute NaOH or Na2CO3 in dioxan-water: J. Chem. Soc.(C)., 2612 (1968). It can also be cleaved by non-aqueous bases, e.g. DBN: J. Chem. Soc., Chem. Commun., 1031 (1972), DBU: Tetrahedron Lett., 25, 2163 (1984), or TBAF in THF: Chem. Lett., 1595 (1987).
