oxygen atom to be transferred approaches from the side of the allylic oxygen functionality (cf. loaded complex A). This additional binding of the bidentate ene diol in the titanium template is also manifested in the enhanced reactivity of the ene diol versus the monodentate allylicalcohols. Nevertheless, the less reactive allylicalcohols also display a high erythro selectivity, provided these monodentate
