An asymmetric synthesis of a 3′-deoxy-3′-18F-fluorothymidine (18F-FLT) precursor has been developed wherein the deoxysugar moiety was synthesized using a novel Ga-mediated allylation of (R)-2,3-cyclohexylideneglyceraldehyde as the key step. The synthesis deviates significantly from the previous syntheses of the 18F-FLT precursors wherein the expensive starting material, thymidine was used.
已经开发了3'-脱氧-3'- 18 F-氟胸苷(18 F-FLT)前体的不对称合成,其中使用新的Ga介导的(R)-2,3-环己基甘油醛的新型烯丙基化来合成脱氧糖部分作为关键步骤。该合成明显不同于先前的18 F-FLT前体的合成,其中使用了昂贵的起始原料胸苷。
