a stereogenic axis as the unique source of chirality. They display chelate binding towards Rh(I) centres affording cationic complexes which have been inspected for their catalytic activity in several asymmetric reactions with modest success. The Pd catalyst derived from the sulfur-containing oxazoline 6a provides up to 66% e.e. in the allylic alkylation of 1,3-diphenylallyl esters with dimethyl malonate
