migration has been used to form silylenolethers with Z-configurational control. The silyl migration also creates a new anion center at sulfur, which can subsequently react with electrophiles to generate Z-silyl enolethers with diverse thioether linkages. The synthetic utility of this pathway was demonstrated by modifying the Z-silyl enolethers with aldehydes via a Mukaiyama aldol reaction or Prins
