摘要：

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. (C) 2004 Elsevier Ltd. All rights reserved.
