Reaction of 3-oxo-3-R1-N-R2-propanethioamides with 2-amino-5-R-pyridines
摘要:
Direction of a reaction between 3-oxo-3-R-1-N-R-2-propanethioamides and 2-amino-5-R-pyridines in acetic acid depends on the structure of initial thioamides: at R-1 = Me, R-2 =Ar, Et 2-methyl-7-R-4H-pyrido[1,2-a]-pyrimidine-4-thiones are obtained, and at R-1 = Ar, R-2 = Me form 1-methyl-5-(N-methylaminothiocarbonyl)-4,6diaryl- 1,2-dihydropyridine-2-thiones.
