Synthesis of New Thiazolidinone Nucleoside Analogues

Abstract
The synthesis of new thiazolididone nucleoside analogues is described. Among the different proposed synthetic pathways, the condensation of various nucleic bases using TMSOTf and Et3N as coupling reagents on a key sulfoxide thiazolidinone intermediate led to the desired compounds in a one-pot procedure. Analytical data and NMR studies confirmed the proposed structure assignment for these compounds.
