A highly regio- and stereoselective route to d- and l-cyclohexenyl nucleosides has been devised, using the Tsuji-Trost reaction as the key step. Contrarily to the widely accepted mechanism (involving a net retention of configuration), the reaction proceeded in a highly stereoconvergent manner, providing cis nucleosides regardless of the relative configuration of the starting materials.
