ABSTRACT

A family of arylspiroborate compounds has been prepared from 2,3-dihydroxynaphthalene and characterized fully using multinuclear NMR spectroscopy and elemental analyses. Single crystal X-ray diffraction studies were carried out on the tetramethylammonium (4) and calcium (6) derivatives. Compound 6 represents the first structurally characterized example of a calcium arylspiroborate salt. All compounds showed modest antifungal and antimycobacterial activities. These results have revealed a new class of compounds that should be further developed to design more potent and selective antitubercular agents. © 2013 Wiley Periodicals, Inc.
