## Abstract A six‐step asymmetric total synthesis of (20__S__)‐camptothecin (**1**) has been accomplished in 25% overall yield starting from the known pyridone **3**. The key steps in this synthesis are the chemoselective Ni‐catalyzed hydrogenation of 3‐cyanopyridone **6** to 3‐formylpyridone **7**
