| Abstract | Hexahydro-1,3,5-triazines have been prepared previously by the reaction of organic isocyanates and isothiocyanates with thiourea, alkali metal cyanates, amidines, imines, enamines and imidates. Solvent-free preparation of tris-pyrazoliy1,3,5-triazines as well as various camphor derived oxazolineazomethine imines and the synthesis of solution phase combinatorial library of 4,6-diamino1,2-dihydro-1,3,5-triazines were reported recently. Moreover, sequential aza-Wittig/cycloaddition/ringtransformation reactions leading to one-pot synthesis of novel 1,3,5 triazine derivatives are also known. In this paper, we report the synthesis of hexahydro1,3,5-triazines 3a-m from the reaction of N-substituted-α-aminoisothiocyanates 2a-m with toluene-2,4diisocyanate. N-substituted-α-amino-isothiocyanates 2a-m were obtained by the addition of ammonium thiocyanate/acetic acid to azomethines 1a-m. |
