shows a new signal at 7.50 ppm attributed to the phenyl ring of α-benzylamine-PSar (Figure ). Neopentylamine modified PSar (α-neopentylamine-PSar) shows the significant shift of the signal 10' at 0.89 ppm (attributed to free neopentylamine) to 1.04 ppm (signal 10), confirming the successful functionalization (Figure ). PPM with dansylcadaverine was performed in DMSO under the same conditions following purification by precipitation from cold diethyl ether utilized conditions are enough for complete PSar oxidation) or to the presence of the residual alcohol.
