Synthesis of purine and 2-aminopurine conjugates bearing the fragments of heterocyclic amines at position 6
摘要:
A series of novel N-(purin-6-yl)- and N-(2-aminopurin-6-yl) derivatives of heterocyclic amines was synthesized. It was found that preferred preparative method for N-(purin-6-yl) derivatives of heterocyclic amines is interaction of 6-chloropurine with heterocyclic amines without any catalyst; whereas N-(2-aminopurin-6-yl) derivatives were obtained in the moderate-to-high yields while heating 2-amino-6-chloropurine and heterocyclic amines in water in the presence of sulfuric acid.
