摘要

A novel application of Pd0-catalyzed arylation to mono N-arylated piperazines, its mechanism, and its application towards the novel syntheses of the key differentially N, N′- diarylated piperazine antifungal intermediate N-(4-hydroxyphenyl)-N′-(4-aminophenyl) piperazine 5 as well as posaconazole 1 are described.
