| titleOfInvention | PROCESS FOR PREPARING AN AMINO ACID OR PEPTIDES WITH ONE OR MORE PROTECTED GUANIDINO GROUPS. |
| abstract | Prodn. of amino acids or peptides contg. one or more protected guanidino gps. is effected by reacting an amino acid or peptide contg. one or more guanidine gps. with a reactive deriv. (I) of a tri(1-5C alkyl) benzenesulphonic acid. (I) is a 2,4,6-trialkylbenzenesulphonyl halide, esp. mesitylenesulphonyl chloride (MSSCl). Protection is effected at -10 to +25 (esp. -5 to +10)deg. C in the presence of 1-10 (esp. 1-5) equivs. of a base and an aprotic polar solvent. Deprotection is pref. effected with a 1-3C alkanesulphonic acid or halosulphonic acid. |
