The reaction of ribonuclease A with either 6-chloropurine riboside 5'-monophosphate or the corresponding nucleoside yields one derivative, with the reagent covalently bound to the alpha-amino group of Lys-1, called derivative II and derivative E, respectively. We studied by means of
On the basis of our previous study on antiviral agents against the severe acute respiratory syndrome (SARS) coronavirus, a series of nucleoside analogues whose 5'-hydroxyl groups are masked by various protective groups such as carboxylate, sulfonate, and ether were synthesized
Reaction of the lithiated species of 9-(2,3,5-tris-O-tert-butyldimethylsilyl-beta-D-ribofuranosyl)-6-chloropu rine with Me3SiCl or Bu3SnCl was found to furnish the corresponding C-2 substituted product, as a result of silyl or stannyl migration from C-8 to C-2 position.
