[reaction: see text] The antitubercular nucleoside antibiotics 1 and 2 were recently described that inhibit the adenylate-forming enzyme MbtA and disrupt biosynthesis of the virulence-conferring siderophore known as mycobactin in Mycobacterium tuberculosis. Herein, we report efforts to refine this inhibitor scaffold by replacing the labile acylsulfamate linkage (highlighted) with the more chemically
