The reaction of 4,4,4-trifluoro-3-oxobutanoates with the corresponding electron-rich amino heterocycles was investigated. A simple and flexible general procedure for the regiospecific annulation of the trifluoromethylpyridine ring to electron-rich amino heterocycles was proposed. A set of CF3-containing fused pyridines in almost quantitative yield was obtained.
