摘要：

Reaction of purine and 2-methyl-and 8-methylpurine with potassium amide in liquid ammonia leads to the formation of adenine and 2-methyl-and 8-methyladenine, respectively. 6-Methyl-and 6, 8-di-tert-butylpurine do not react. It was proven by applying 15N-labeled potassium amide that the amination reactions do not involve opening of the pyrimidine ring. Low temperature NMR spectroscopy showed that in solutions of purine and 2-methylpurine in potassium amide-liquid ammonia an anionic a complex at position 6 is formed. 8-Methylpurine on the contrary only showed the presence of a monoanion and a dianion. © 1979, American Chemical Society.
