説明

The reaction conditions for the one-step synthesis of purine by heating formamide were investigated. Purine was formed as a main product when formamide was heated at 175-185° in a sealed vessel ; reaction temperatures above 190° and prolonged heating resulted in decreased purine yields. Purine was not produced when the reaction was performed below 160°, but the introduction of hydrogen cyanide to the reaction vessel gave purine along with adenine, a major product. This indicates that hydrogen cyanide is an essential key intermediate in purine ring formation. A reaction mechanism for purine formation is also proposed.
