Cytidine has been converted into l-(5-amino-5-deoxy-j8-D-arabinofuranosyl) cytosine by a sequence of reactions involving A-benzoylation, sulphonation, acetylation, displacement with azide ion, e/c., and l-(3-amino-3-deoxy-jS-D-arabinofuranosyl)-6-azauracil was derived from 2, 3 -di-0-methanesulphonyl-5 -O-trityl-6-azauridine via 2,2 - and 2, 3 -anhydro-nucleosides. Other syntheses have been accomplished by the condensation of an appropriately derivatized amino-sugar with either a pyrimidine or purine derivative for example, the Hilbert route was used to prepare l-(2-amino-2-deoxy-a-D-arabino- and -jS-o-xylo-furanosyl)cytosine. > The reactivity of l,3,4,6-tetra-0-acetyl-2-acyl-amido-2-deoxy-j3-D-glucopyranoses in condensation reactions with 2,6-dichloro-purine, theophylline, and 6-benzylaminopurine was shown to be in the order benzamido > acetamido > phthalimido. 9-(3-Acetamido-2,5-di-0-acetyl-3-deoxy-j8-D-ribofuranosyl)-2,6-dichloropurine has been synthesized and converted into the corresponding 2,6-diamino- and 6-amino-2-chloro(fluoro)-nucleosides. ...
