The synthesis of a pyrimidine analog, 3 0 -deoxy-3 0 -[ 18 F]-fluoro-1-b-d-xylofuranosyluracil ([ 18 F]-FMXU) is reported. 5-Methyluridine 1 was converted to its dimethoxytrityl derivatives 2 and 3 as a mixture. After separation the 2 0 , 5 0 -di-methoxytrityluridine 2 was converted to its 3 0 -trif
In a continuing program for the synthesis of oligosaccharides that occur as part of mutinous glycoconjugates, we previously described\* the synthesis of the disaccharide methyl 3-0-(2-acetamido-2-deoxy-P-D-glucopyranosyl)-a-D-galactopyranoside (1). We have also demonstrated that 1 could be readily
