Alternative spiroketalization methods toward purpuromycin: A hemiketal conjugate addition strategy and use of an electron-rich isocoumarin precursor

Two methods are presented that were designed to circumvent the persistent problem of benzofuran formation and instead yield a spiroketal of the rubromycin family type. First, using an alternative disconnection, a hemiketal conjugate addition to a naphthaq
