The unconventional methodology for the non-epimerizable cycloacetalization of optically active (1S,2S)-2-amino-1-(4-nitrophenyl)propane-1,3-diol (p-nitrophenylserinol) (condensed H2SO4 96% as solvent and catalyst, i.e., sulfuric transacetalization) p

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 commercia

Our group has developed a stereospecific enzymatic method, which is very efficient for the in vitro synthesis of l-[(15)N]serine, l-[(15)N]methionine and l-[(15)N]glutamic acid. These amino acids were prepared from the corresponding alpha -ketoacids

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 stereochemis

The first use of a spiranic diamino-nucleophile, 7,11,18,21-tetraoxa-3,15-diazatrispiro[5.2.2.5.2.2]heneicosane, as linker in the synthesis of dendritic melamines, is reported. The chirality of a C(a)4 and/or a C(a)2(b)2 spiranic carbon is discussed
