Abstract

The 2,2,2-trichloroethoxycarbonyl (Troc) group attached at the <I>N</I><SUP>in</SUP> function of tryptophan by acylation with Troc-Cl in the presence of a catalytic amount of tetra-<I>n</I>-butylammonium hydrogensulfate can be quantitatively removed either by cadmium dust in acetic acid or under basic conditions, e.g., hydrazine hydrate and NaOH, but is resistant to strong acidic conditions.
