Synthesis of Arylated Pyrazoles by Site-Selective Suzuki-Miyaura Reactions of Tribromopyrazoles

[摘要]：The first Suzuki-Miyaura reactions of N-protected tri-bromopyrazoles are reported. Their reaction with three, two, or one equivalents of arylboronic acids afforded 3,4,5-triarylpyrazoles, 3,5-diaryl-4-bromopyrazoles, or 5-aryl-3,4-dibromopyrazoles, respectively. All reactions proceeded with very good site-selectivity.
