Vital to life as we know it—pyrimidine and purine bases are included in the structures of DNA and RNA. Purine is a heterocyclic aromatic organic compound, consisting of a pyrimidine ring fused to an imidazole ring. Purines, including substituted purines and their tautomers, are the most widely distributed kind of nitrogen-containing heterocycle found in nature, have vast biological applications and are useful as medicinal chemistry building blocks. The presence of a halogen allows these reagents to be used as substrates in various coupling reactions, including Suzuki-Miyaura cross-coupling reactions.
