Functionalized carbo- and hetero-cyclic compounds are widely found in natural products and other bioactive molecules, which are also important scaffolds with significant synthetic value. The cyclization of 1,n-enynes is one of the most atom-economic and efficient approaches. In particular, the palladium-catalyzed cyclization of 1,6-enynes has been extensively studied and has achieved significant advancements. This review focuses on the cyclization of 1,6-enynes initiated by nucleopalladation of alkynes, including hydropalladation, carbopalladation, halopalladation and oxypalladation. It was classified by the nucleopalladation and the recent developments in palladium-catalyzed 1,6-enyne cyclization over the past two decades are systematically summarized. Special emphasis is placed on the asymmetric reactions, and reaction mechanisms, along with further prospects of this field.

Key words: palladium catalysis, 1,6-enynes, cyclization reaction, nucleopalladation, carbocyclic compounds, heterocyclic compounds
