Rezumat: DOI: 10.24193/subbchem.2020.1.04 Published Online: 2020-03-30 Published Print: 2020-03-30 pp. 39-54 VIEW PDF: FULL PDF Starting from etheric type derivatives of 4-aminophenol, namely (4-aminophenoxy)acetic acid or 4-(4-aminophenoxy)butyric acid and 4-(n-octyloxy)aniline, we report herein two routes of access to two novel N-substituted amphionic melamines with the tandem 4-(1-carboxy-n-alkoxy) phenyl/4-(n-octyloxy)phenyl units against the piperazin-1-yl group, as a basic site. The successful SN2-Ar aminations of cyanuric chloride performed with these amine-nucleophiles are discussed in terms of chemoselectivity, mainly in the third step of the synthesis, implying piperazine as such or its N-Boc-mono-protected form. The amphionic nature of the targeted melamines was fully confirmed both in solution (VT-NMR) and in the solid state (IR). Keywords: (4-aminophenoxy)acetic acid, 4-(4-aminophenoxy)butyric acid, amphionic melamines, N-Boc-piperazine, 4-(n-octyloxy)aniline. |
