Morphinans are essential medicines derived entirely from poppy supply chains rendered increasingly volatile by climate change. Here, we report a seven‐step, asymmetric chemical synthesis of (−)‐codeine from simple materials that requires a total combined reaction time of fewer than 24 hours. The efficiency of our approach arises from a double‐Heck cyclization reaction that generates two rings and...
