Tritylamines, protection

Meisenbach M, Voelter W (1997) New methoxy-substituted tritylamine linkers for the solid phase synthesis of protected peptide amides. Chem Lett 1265— 1266... 

Tritylamines can serve as both linkers and protective groups for aliphatic amines because, unlike benzhydrylamines, they do not usually undergo acylation when treated with activated acid derivatives. Tritylation of aliphatic amines is readily accomplished by adding excess amine to a support-bound trityl chloride. Illustrative cleavage reactions are listed in Table 3.21.
