  Derivatization of a tris-oxazole using Pd-catalyzed coupling reactions of a 5-bromooxazole moiety

  摘要：

  Modification at the C5 position of an oxazole ring contained in a 2,4-concatenated tris-oxazole by Pd-catalyzed coupling reactions was performed. Novel Pd-catalyzed amination and alkoxylation of a 5-bromooxazole derivative as well as Suzuki-Miyaura coupling and Migita-Stille coupling have been demonstrated. A wide variety of functional groups, including aryl, heteroaryl, primary and secondary amines, and phenol, were introduced in the 5-bromooxazole moiety in moderate to excellent yields using Pd(OAc)(2)/S-PHOS or Pd(OAc)(2)/X-PHOS as a catalyst.
