  Synthesis of Pyrimidinyl Triflates and Palladium-catalyzed Coupling with Organotion and Organozic Reagents

  摘要：

  Pyrimidinyl triflates have been synthesized from pyrimidinones using triflic anhydride in the presence of triethylamine. The triflates, in the pyrimidine electrophilic positions, are versatile intermediates for substitution reactions. Carbon substituents are readily introduced in any position by Pd-catalyzed coupling reactions between pyrimidinyl triflates and aryl- or alkenyltin or with the corresponding organozinc reagents. Organozinc reagents are generally more reactive in coupling reaction and will effect the introduction of alkyl substituents.
