General trends in reaction of N-aryl-3-oxobutanethioamides with 2-aminoazoles(azines)
摘要:
Reaction products obtained from N-aryl-3-oxobutanethioamides and 2-aminoazoles(azines) are derivatives of (arylamino)pyrimidines and pyrimidinethiones. The ratio of the products depends on the basicity of 1,3-binucleophiles, acidity of the medium, and the character of substituents in the phenyl ring of initial thioamides.
