Reactions of 3,3,3-Trifluoropyruvates with Amidines - New Trifluoromethyl Substituted Heterocyclic "Building Blocks"
Sewald, N.,Burger, K.
, p. 899 - 908 (1993)
4-Hydroxy-4-trifluoromethyl-2-imidazolin-5-ones are obtained in good yields upon reaction of 3,3,3-trifluoropyruvates with amidines.Subsequent treatment of these heterocycles with thionyl chloride gives 4-chloro-4-trifluoromethyl-2-imidazolin-5-ones which proved to be versatile trifluoromethyl substituted building blocks.Substitution of chloride is feasible with a variety of hetero and carbon nucleophiles.Ring expansion with diazo compounds affords trifluoromethyl substituted pyrimidines. - Keywords. 3,3,3-Trifluoropyruvates; Amidines; 4-Trifluoromethyl-2-imidazolin-5-ones; Trifluoromethyl substituted pyrimidines.
