Palladium catalysts possessing pyridineoxazoline ligands were found to catalyze the chain-walking cycloisomerization of 1,n-dienes to form five-membered rings and were particularly effective for the reaction of 1,14-dienes. Asymmetric synthesis of cyclopentane derivatives was also achieved for the reaction of 1,n-dienes using chiral pyridineoxazoline ligands.
