A concise and stereoselective synthesis of exiguaquinol dessulfate is described. Sequential application of a Diels–Alder cycloaddition, a desymmetrizing aldol addition, and a reductive Heck cyclization established most of the architecture of exiguaquinol, and a carefully choreographed introduction of the polar substituents afforded the title compound; unfortunately, naphthoquinol sulfation could not be achieved to deliver exiguaquinol. Our hypothesis regarding the configurational preference of the N-acyl hemiaminal, which was based upon an analysis of internal hydrogen-bonding interactions with polar functional groups, was proven correct. Unfortunately, the title compound did not demonstrate any bactericidal activity against H. pylori cultures. A desymmetrization strategy led to the synthesis of a congener of exiguaquinol, an inhibitor of the H. pylori MurI enzyme and a potential antibiotic. The pentacyclic architecture was accessed via convergent Diels–Alder and aldol additions, followed by a reductive Heck cyclization to forge the vicinal quaternary stereogenic centers.
