Díaz, Jimena E.,Bisceglia, Juan á.,Mollo, Ma. Cruz,Orelli, Liliana R.
, p. 1895 - 1897 (2011/04/25)
In the present Letter we report the use of N-arylputrescines as synthetic intermediates for the preparation of N-acyl-N′-aryltetramethylenediamines 3 and related seven-membered heterocyclic amidines 4. Compounds 1 were synthesized by Cs2CO
New synthetic route for selectively substituted 1,n-diamines. Synthesis of N-aryl tetra- and pentamethylenediamines
Ramirez, María A.,Corona, María V.,Blanco, Maria M.,Perillo, Isabel A.,Porcal, Williams,Salerno, Alejandra
experimental part, p. 5000 - 5002 (2011/02/21)
A general procedure for the synthesis of N-aryltetra- and pentamethylenediamines 1 by acid hydrolysis of N-aryl-N'-acylalkylenediamines 2 under microwave irradiation is described. The precursors 2 are obtained by amination of the corresponding N-(x-haloal
1H-4,5,6,7-tetrahydro-1,3-diazepines. Part I: Synthesis, spectral and chemical properties of 1,2-diaryl derivatives

The synthesis of several 1,2-diaryl-1H-4,5,6,7-tetrahydro-1,3-diazepines 1 by cyclization of N-aryl-N′-benzoyltetramethylenediamines 2 is described. Two alternative synthetic routes to obtain precursors 2 are discussed, being that which employes pyrrolidine as starting material the most convenient. Nucleophilic attack of compounds 1 on methyl iodide affords 1,2-diaryl-1H-4,5,6,7-tetrahydro-1,3-diazepinium iodides 3. 1H-nmr spectra of these compounds are unequivocally assigned by means of NOESY experiments. 1H-nmr spectra of compounds 1 and 3 are analyzed and compared inter se and with those of compounds 1 run in the presence of trifluoroacetic acid-d. Reduction of compounds 1 with borane leads regiospecifically to N-aralkyl-N′-aryltetramethylenediamines 7.
