A highly enantio‐ and diastereoselective thiourea‐catalyzed dearomatization of isoquinolines employing N‐tert‐butylhydrazones as neutral α‐azo carbanions and masked acyl anion equivalents has been developed. Experimental and computational data supports the generation of highly ordered complexes wherein the chloride behaves as a template for the catalyst, the hydrazone reagent, and the isoquinolinium
