Abstract

Abstract 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 the Pd-allylic alkylation leading to enantioselectivities of up to 74% ee.
