Starting from 4-piperidone monohydrate hydrochloride (or the hydrochloride of its ethylene ketal) alone, otherwise in tandem with a C-2-substituted 2-aminopropane-1,3-diol ("serinol") as amino-nucleophiles in reaction with cyanuric chloride, the synthesis

The iterative chemoselective amination of cyanuric chloride to dimers of new G-2 dendritic N-substituted-2,4,6-triamino-s-triazines (melamines) having C-2-substituted 2-aminopropane-1,3-diols ('serinols') in tandem with the ethylene ketal of 4-piperidone as peripheral units is reported. The structure as a function of increasing molecular size was studied by NMR spectroscopy, DFT calculation and AFM imaging. A concise nomenclature defining the restricted rotational phenomena about the newly created C(s-triazine)-N(exocyclic) partial double bonds, seen as axes of (pro)diastereomerism, is used. We propose a new form of frontier rotamerism for the dendrimer surface, which operates over a long range.

The novel organic–inorganic nanohybrid magnetic nanoparticles (HNPs@Py) were prepared by a simple method and characterized by FT-IR, XRD, FE-SEM, TGA, VSM, EDX, and MAP. The catalytic activity of this new (HNPs@Py) was studied for green synthesis of bisco
Design, iterative synthesis and structure of novel optically active trispiro-dendritic melamines incorporating 'open-chain' versus 'closed-chain' serinolic peripheral units

Abstract Starting from commercial C-2-substituted 2-aminopropane-1,3-diols (serinols, 'open-chain' peripheral units) and optically active amino-1,3-dioxanes ('closed-chain' peripheral units) as cycloacetals of (1S,2S)-2-amino-1-(4-nitrophenyl)propane-1,3-
New serinolic amino-s-triazines by chemoselective amination of cyanuric chloride and their (pro)diastereomerism in restricted rotational phenomena

The highly chemoselective preparation of new elaborated N-unsymmetrically substituted chlorodiamino-s-triazines and melamines, seen as building-blocks for iterative synthesis, is reported. It consisted of amination of cyanuric chloride with commercial C-2
Serinolic amino-s-triazines: iterative synthesis and rotational stereochemistry phenomena as N-substituted derivatives of 2-aminopropane-1,3-diols

The iterative synthesis of 2,4,6-triamino-s-triazines (melamines), precursors and dendritic structures, by amination of cyanuric chloride with C-1 versus C-2-substituted 2-aminopropane-1,3-diols (serinols), is comparatively examined. The stereochemistry o
