    • They-amino functions of these building blocks anchored on the resin give a clear positive Kaiser ninhydrin test, so this test is useful in controlling the synthesis of this kind of peptide. Kaiser, E.; Colescott, R L.; Bossinger, C. D.; Cook, P. I. Anal. Biochem. 1970, 34, 594-598.

    • Although the De Clercq test seems more sensitive than the the chloranil test (De Clercq gives slightly positive when chloranil gives negative), the final product whose synthesis has been controlled by just the chloranil test is good to excellent.

    • This different intensities of the CD bands between 2 and 4 could be related to the presence of an aromatic side chain in 4 or to the increased bulkiness of the substituents.
