Abstract: Supported Pd nanoparticles catalyzed the reductive cycloisomerization of diynes to give 1,3‐dienes, and subsequent intermolecular [4+2] cycloaddition with dienophiles led to cyclohexene derivatives. Various diynes and dienophiles participated in the one‐pot reaction to give the corresponding products in good to high yields. Al2O3‐supported Pd catalysts were highly tolerant toward air and reusable.
