    • Significant shifts downfield for the peaks corresponding to the methyl and methylene protons on carbons directly attached to the nitrogens of the acid building blocks suggest that the tertiary amines are protonated. Therefore, the building blocks must be overall zwitterionic, given that they are prepared and isolated in nonacidic conditions. Such pH-dependent shifts are expected for strongly basic systems.

    • Our stock of 21d was supplemented by an independent pathway, alkylation of commercially available hordenine sulfate with N-Boc-3-bromopropylamine (50% yield), to compensate for the low yield obtained in the reductive aminolysis.
