Diastereocontrol in glycosylation reactions: Synthesis of β-D and β-L dideoxycytidine analogues
摘要:
Expeditious and diastereoselective total syntheses of the antiviral agents, beta-L-ddC, beta-L-5FddC and beta-D-5FddC have been achieved in four steps from commercially available R-(-)-5-oxo-2-tetrahydrofurancarboxylic and its 2S isomer respectively.
