found and used for the enantioselective synthesis of bisbenzannulated spiroketals, the bioactive core of rubromycins, with high levels of enantioselectivity (up to 98% ee) via an organohalogenite‐mediated asymmetric intramolecular aromatic spiroketalization. This is the first organocatalytic method for the construction of optically pure bisbenzannulated spiroketals.
