SUGARS WITH POTENTIAL ANTIVIRAL ACTIVITY .3. ISOLATION OF ANOMERIC 6-BENZAMIDO-9(1',2'-5',6'-DI-O-ISOPROPYLIDENE-D-MANNOFURANOSYL) PURINES SOME (1',5'-DIALDOFURANOSYL) NUCLEOSIDES AND RELATED COMPOUNDS

The reaction of 1,2:5,6-di-O-isopropylidene α-d-mannofuranosyl chloride with chloromercuri-6-benzamidopurine gives a mixture of α- and β-isomers m the ratio 39α:14β, Both isomers have been isolated as pure crystalline compounds. Some further extensions of the reaction are described, together with attempts to make nucleosides containing free aldehydo- groups. © 1969.
