Synthesis of 4-Aryl and Unsymmetrical 4,6-Diarylpyrimidines by the Suzuki-Miyaura Cross-Coupling Reaction
摘要:
A two-step procedure for the synthesis of 4-arylpyrimidines from inexpensive 4,6-dichloropyrimidine via a Suzuki-Miyaura/hydrodechlorination reaction sequence is described. The reaction resulted in the predominant formation of mono-arylated product. The cross-coupling of 4-chloro-6-substituted pyrimidines with various aryl/heteroarylboronic acids also furnished 4,6-disubstituted pyrimidines in acceptable yields.
