Pterin chemistry. Part 88†. A simple synthesis of 5-Deoxy-L-[5-2H1]arabinose and L-[3′-2H1] biopterin

A simple synthesis of 5-deoxy-L-[5- 2 H 1 ]arabinose was performed to obtain L-[3'- 2 H 1 ]biopterin. The reduced form of this model substance is needed to investigate the pathway of 7-substituted pterins in patients with primapterinuria
