PROTECTED AMINO-ACIDS AND PROCESS FOR THEIR PREPARATION

Compounds of the formula I in which n stands for 1 or 2, R1 denotes hydrogen or an amino protective group, R2 denotes hydrogen or a carboxyl protective group and R3 denotes triphenylmethyl, 4-monomethoxytrityl or 4,4'-dimethoxytrityl, and reactive carboxylic acid derivatives of those compounds...

Zusammenfassung:Compounds of the formula I in which n stands for 1 or 2, R1 denotes hydrogen or an amino protective group, R2 denotes hydrogen or a carboxyl protective group and R3 denotes triphenylmethyl, 4-monomethoxytrityl or 4,4'-dimethoxytrityl, and reactive carboxylic acid derivatives of those compounds of the formula I in which R2 stands for hydrogen are described. These compounds can be used as starting substances for the preparation of peptides. They are better suited for this than analogous compounds of the formula I in which R3 denotes hydrogen, or one of the hitherto customary carbamoyl protective groups.
