N-Acetyl-Dgalactosamine uridine diphosphate ester of uridine diphosphate ester of... [Pg.246]

The reaction of adenosine with 2-acetoxy-2-methylpropanoyl chloride or the corresponding bromide is less regioselective than that of uridine,400 and gives 9-(2-0-acetyl-3-deoxy-3-halo-/3-D-xylofuranosyl)-and9-(3-0 - acetyl - 2 - deoxy - 2 - halo - /3 - D - arabinofuranosyl) - adenine,... [Pg.84]

A solution of 5 -0-acetyl-2 3 -0-isopropylidene-3-nitrouridine [44, prepared from 5 -0-acetyl-2 3 -0-isopropylideneuridine and nitronium triflu-oroacetate (91JOC7038)] in acetonitrile gave, when treated with an acetonitrile-water solution of N-ammonium choride, potassium hydroxide, and triethylamine for 5 days, 5 -(9-acetyl-2 3 -(9-isopropylideneuridine (45) in 73% yield. It contained the label at position 3. Deprotection of the O-acetyl and O-isopropylidene groups by methanol/hydrochloric acid gave [3- N]uridine (46) (Scheme III.26). [Pg.113]

The intravenous injection of 2-amino-2-deoxy-D-glucose-14C into rats, and subsequent isolation of the uridine diphosphate N-acetyl-hexosamine fraction, has been suggested as a fast and convenient method for preparing small amounts of a mixture of radioactive uridine 5 -(2-acetamido-2-deoxy-a-D-gIucopyranosyl pyrophosphate) and uridine 5 -(2-acetamido-2-deoxy-a-D-galactopyranosyl pyrophosphate). [Pg.343]
