MOLECULAR CONFORMATION OF 1,3-PYRIDYLPHENYLUREAS BY 1H AND 13C NMR STUDY
Sudha, L. V.,Sathyanarayana, D. N.
, p. 141 - 146 (1985)
1H and 13C NMR spectra are reported for several 1,3-pyridylphenyl ureas.Analysis of the spectra yielded the chemical shifts.The variations in the chemical shifts have been discussed in terms of the molecular conformations.
Synthesis of new unsymmetrical 4,5-dihydroxy-2-imidazolidinones. Dynamic NMR spectroscopic study of the prototropic tautomerism in 1-(2-benzimidazolyl)- 3-phenyl-4,5-dihydroxy-2-imidazolidinone

The acid-catalyzed cyclocondensation in refluxing acetonitrile of aqueous glyoxal with N-heteroaryl-N′-phenylureas 4a-f (heteroaryl = 2-thiazolyl, 2-pyrimidinyl, 2-pyrazinyl, 2-pyridinyl, 3-pyridinyl and 2-benzimidazolyl) led to the formation of the corre
Synthesis of N-phenyl-N′-pyrimidylurea derivatives by selenium- or selenium dioxide-catalyzed reductive carbonylation of nitroaromatics

, p. 3446 - 3452 (2007/10/03)
Forty unsymmetric N-phenyl-N′-pyrimidylurea derivatives were synthesized in moderate-to-good yields by one-pot reductive carbonylation of nitroaromatics using selenium or selenium dioxide as the catalyst, aminopyrimidine derivatives as co-reagents, and ca
