Application

Sodium tert-butoxide may be used as a safe and effective alternative to sodium hydride for the coupling of hydroxyethyl adenine with diethyl p-toluenesulfonyloxymethanephosphonate to form 9-[2-(diethylphosphonomethoxy)ethyl]adenine (diethyl-PMEA), which is a key intermediate to prepare adefovir dipivoxil.
It can also be used:
  • To facilitate the coupling of aryl halides with benzene derivatives in the presence of 10-phenanthroline derivative.
  • To activate first-row transition-metal pre-catalysts.
  • As a base for the amination of aryl chlorides in the presence of a novel palladacyclic precatalyst.
