Resumo

In the presented work, the reaction of two 2-hydroxy-5-methylacetophenone chalcones and guanidine was investigated in the presence of hydrogen peroxide. Depending on the structure of the chalcones a 4.6-diaryl-2-aminopyrimidine or flavanol was obtained. The structures of the obtained products were elucidated by NMR spectroscopy and X-ray crystallography. Reaction route formation of compounds was proposed.
