The discovery of thio- and fluoro-nucleosides as antiviral or anticancer agents Prompts us to explore the synthesis of acyclic analogous. In this paper is reported the preparation of acyclothionucleosides by the alkylation of nucleic bases with difluorothio-esters and -alcohols. Compounds Structurally Close to known antiviral agents were tested towards a large variety of Viruses. (c) 2008 Elsevier B.V. All rights reserved.
Fluorination of α,α-dichlorosulfides: access to gem-difluorothioethers as useful building blocks
The synthesis of alkylsulfanyidifluoro-acetate and ketones by the Halex reaction is described. The remarkable reactivity of thiodifluoroacetate derivatives opened rapid access for the preparation of useful building blocks such as gem-difluoroketones and amides. (C) 2003 Elsevier Science Ltd.
