    Abstract:
    A series of twenty one Schiff bases based on boronate ester of 1,2-O-isopropylidene-α-d-xylofuranose scaffold were designed and synthesized by condensation of formyl or amino phenyl boronate esters with substituted anilines or 2-hydroxybenzaldehydes, respectively. All the imines are remarkably stable crystalline solids and were obtained in good yields. All the products were fully characterized by FT-IR, multinuclear NMR ((1)H, (13)C and (11)B) spectroscopy, and elemental analysis. Furthermore, the molecular structures of two of the Schiff bases were established by single crystal X-ray diffraction analysis. All the compounds have been screened for in vitro antimicrobial activity against various Gram-positive and Gram-negative bacterial and fungal strains. They exhibited moderate to good inhibitory activity against most of the tested organisms in comparison with standard drugs.
