Benzoxazoles being structurally similar to bases adenine and guanine interact with biomolecules present in living systems. These compounds possess antimicrobial, central nervous system activities, antihyperglycemic potentiating activity, analgesic, and anti-inflammatory activity. It can also be used as starting material for other bioactive molecules. Modifications in structure and the biological profiles of new generations of benzoxazoles were found to be more potent with enhanced biological activity. Considering all these, we have prepared this review and discussed the synthesis and biological activities of benzoxazoles.

“…Facile synthesis of 2-substituted benzoxazoles via ketenes reported by Olagbemiro et al [44]. The generation of diphenyl-, phenyl-, phenoxy-, and chloroketenes by the treatment of corresponding acid chlorides with triethylamine in the presence of 2-aminophenol resulted in good yields of 2-substituted benzoxazoles (75).…”
