A general approach to the synthesis of 5-S-functionalized pyrimidine nucleosides and their analogues

Abstract

A general and efficient approach was developed for the introduction of S-functionality at the C-5 position of cytosine and uracil nucleosides and their analogues. The key step is a palladium-catalyzed C–S coupling of the corresponding 5-bromo nucleoside derivative and alkyl thiol. The butyl 3-mercaptopropionate coupling products were further converted to the corresponding disulphides, the stable precursors of 5-mercaptopyrimidine nucleosides.
