Using a combination of NMR, UV-Vis, circular dichroism (CD) spectroscopy, and EPR, we elucidated the formation mechanism of these compounds and explored their optical properties. Furthermore, CD spectra showed a pattern that correlates with their configurations: DADQs with R configuration showed negative CD signals in methanol and DMSO, whereas DADQs with S configuration showed positive CD signals. The DADQs with aromatic side chains reversed their CD signals in relatively nonpolar solvents. These findings indicate that chirality can be effectively transferred from primary amines to DADQ, offering a potential method for determining the absolute configurations of primary amines.
