摘要

Treatment of 5'-S-(alkyl and aryl)-5'-thioadenosine derivatives 2 with XeF2, or the corresponding sulfoxides 3 with DAST/SbC13, gave diastereomeric 5'-flUOrO compounds which were deprotected to give the 5'-S-(alkyl and aryl)-5 '-fluoro-5'-thioadenosine analogues 5. Stereochemistry was established by X-ray crystallography, and 19F NMR chemical shifts were definitive for configurationally-related 5'-flUOr0 diastereomers. ...
