Amines by all means: A unique aza‐Rauhut–Currier/cyclization/desulfonation cascade reaction between allenoates and N‐sulfonyl‐1‐aza‐1,3‐dienes, catalyzed by the readily available diamine TMEDA, has been developed. This strategy provides facile access to a broad range of valuable highlyfunctionalized pyridines in good yields under very mild reaction conditions.
