Abstract:2-Amino-4,6-disubstituted-sym-triazines containing sterically hindered phenol segments were synthesized by cyclocondensation of N-acrylguanidines with nitriles or thiocyanates. The same compounds can be obtained by condensation of N-acylguanidine with iminoester hydrochlorides. The reaction of methyl Bgr-(4-hydroxy-3,5-di-tert-butylphenyl)propionate with biguanides gives N-substituted 2,4-diamino-6-R-sym-triazines that contain a shielded phenol residue.For Communication 5, see [1].Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 10, pp. 1392–1397, October, 1987.
