Cyclopenta[b]thiophene-alkyloxazolines: New nitrogen-sulfur hybrid ligands and their use in asymmetric palladium-catalyzed allylic alkylation

New chiral nitrogen and sulfur containing hybrid ligands have been prepared and fully characterized. Their structure includes cyclopenta[b] tiophene and oxazoline moieties as sources of chirality. Their catalytic activity has been tested successfully in t
