A Ferrier-Type Allylic Rearrangement of 3′-Deoxy-3′,4′-didehydronucleosides Mediated by DMF Dimethyl Acetal: Direct Access to 4′-Alkoxy-2′,3′-didehydro-2′,3′-dideoxynucleosides
A straightforward synthesis of epimeric 4′-alkoxy-substituted 2′,3′-didehydro-2′,3′-dideoxynucleosides via a DMF dimethyl acetal mediated allylic rearrangement of 3′-deoxy-3′,4′-didehydronucleosides is described.
The invention provides compounds of the Formula (I) or the Formula (Ia) which are useful intermediates in the synthesis of potential antiviral drugs such as 3'-deoxy-3',4'-didehydro-cytidine triphosphate (ddhCTP).
Straightforward synthesis of 3′-deoxy-3′,4′-didehydronucleoside-5′-aldehydes via 2′,3′-O-orthoester group elimination: a simple route to 3′,4′-didehydronucleosides
Straightforward, high-yielding syntheses of 3'-deoxy-3',4'-didehydronucleoside-5'-aldehydes and 3'-deoxy-3',4'-didehydronucleosides starting from 2',3'-O-orthoester derivatives of ribonucleosides are described. (C) 2010 Elsevier Ltd. All rights reserved.
