Chemistry and Pharmacology
A high-yield synthesis of [1-15N]-2′-deoxyinosine (5), [4-15N]-2′-deoxyAICAR (7), and [1-15N]-2′-deoxyguanosine (10) from 2′-deoxyinosine (1) using relatively low expensive 15NH3 as 15N source is described. The method exploits 2-C reactivity of 2′-deoxyinosine (1) to obtain its 15N-labelled counterpart, through [1-15N]-2′-deoxyinosine (5), and successively, [4-15N]-2′-deoxyAICAR (7). [1-15N]-2′-Deoxyguanosine (10) can be prepared as well, through an improved cyclization procedure. No protection of sugar hydroxyl groups is required at any stage.
