A rapid and efficient synthesis of 2‐deoxy‐2‐[18F]fluoroacetamido‐D‐mannopyranose and ‐D‐galactopyranose

Abstract
Rapid and efficient syntheses of 2‐deoxy‐2‐[18F]fluoroacetamido‐D‐mannopyranose (1) and ‐D‐galactopyranose (2), respectively, starting from [18F]fluoride and ethyl bromoacetate are described. [18F]Fluoride was produced by the 18O (p, n) 18F nuclear reaction using the cyclotron. The total times required for synthesis of (1) and (2) are ca. 80 min. The radiochemical yield and purity of (1) are an 18% and ≥98%, respectively. Compound (2) is also synthesized with the same radiochemical yield and purity.
