The chemistry of heterocycles has emerged as a fundamental division of organic synthesis which is highly contributed to drug discovery. Structural modification of heterocycles comprises at least half of all organic chemistry research worldwide. Benzazoles, as one class of heterocycles, form the basis of many pharmaceutical, agrochemicals, veterinary, and natural products. Moreover, benzazole derivatives possess a diverse range of biological activities, which make them a good skeletons for drug design. The deisgned introduction of substituents on benzoazole can dramatically alter its biological activity. Fluorine and piperazine are common appendages in valuable therapeutic molecules in medicinal chemistry.

For instance, ciprofloxacin^® (1) is a powerful antibiotic with a broad spectrum of biological activity and its activity was related to the incorporation of fluorine and piperazine¹. Previously, we have successfully synthesized several heterocycles^2-4(2-4) and recently benzoazoles⁵(5-8) bearing fluorine and piperazine as shown in Figure 1.
