  Synthesis of a Novel Aldehyde: 4-O-Methyl-5-formylmethyl- 2′-deoxyuridine

  摘要：

  The synthesis of the blocked nucleoside 3',5'-di-O-p-toluoyl-4-O-methyl-5-formyl-methyl-2'-deoxyuridine (19) was accomplishied in eleven steps from gamma-butyrolactone. This aldehyde, which should facilitate the synthesis of nucleosides containing F-18, was converted to the corresponding blocked dithianyl nucleoside (21), and also to 5-(2,2-difluoroethyl)-substituted derivatives of 2'-deoxyuridine and 2-deoxycytidine.
