one-pot synthesis of A3-corroles via "3 + 4" condensation of an aldehyde with a pyrrole followed by macrocyclization mediated by DDQ. After thorough examination of various reaction parameters (reactivity of an aldehyde, catalyst, solvent, concentration, time etc.) we have elaborated three different sets of conditions for different types of aromatic aldehydes--highly reactive, moderately reactive and sterically
