4-Aminothiazolyl analogs of GE2270 A: Design, synthesis and evaluation of imidazole analogs

Imidazole analogs of the antibiotic natural product GE2270 A (1) were designed, synthesized, and evaluated for Gram positive bacteria growth inhibition. A recently reported, copper-mediated synthesis was exploited to prepare 4-thiazolyl imidazole analogs of 1. The synthesis described represents a structurally complex, natural product-based application of this recently reported synthetic methodology. In addition, the biological evaluation of the imidazole-based analogs further define the SAR of the 4-aminothiazolyl-based antibacterial template.
