Synthesis of functional derivatives of trifluoromethylpyrimidines from acetylacetone, trifluoroacetonitrile, and aryl isocyanates
摘要:
1,1,1-Trifluoro-2-amino-3-acetyl-2-penten-4-one was obtained by the addition of acetylacetone to trifluoroacetonitrile in the presence of catalytic amounts of nickel acetylacetonate. The reaction of 1,1,1-trifluoro-2-amino-3-acetyl-2-penten-4-one with aryl isocyanates gave 1-aryl-5-acetyl-6-methyl-4-trifluoromethyl-1H-pyrimidin-2-ones.

A new approach to CF3-containing 3,4-dihydroquinazolin-2(1H)-ones based on the condensation of 5-acetyl-6-methyl-1-phenyl-4-trifluoromethylpyrimidin-2(1H)-one with dimethylformamide dimethyl acetal has been suggested.
