Abstract

Method G. Coupling with BOP. To a stirred solution of the amino acid eater component (1- 01) in CHzClz (10 mL) were added BOP reagent (1.1 mmol), and diprotected N-(o- aminoalkylenelamino acids (1.1 mmol), DIEA (3 mmol) at room temperature. After 15 min the pH was checked for basicity (in casea where the pH was lower than pH= 9, more DIEA was added) and the reaction mixture left for 1 h at room temperature. The solvent was ...
