This 1 to 3 C-branched aminotriester is stable under mild conditions and can be stored for months at 0 degrees Celsius. Although, caution should be taken in that it can undergo an intramolecular cyclization to give the corresponding lactam with prolonged, elevated temperatures ( > 50 C). Notably, this material has been demonstrated and reported to couple with carboxylic acids, in good yields. using standard peptide conditions and reagents.
