Zinc catalysts supported by chiral diaminophenolate ligands

1 Zinc catalysts supported by chiral diaminophenolate ligands 

When we utilized the chiral proligand in an identical reaction, we 

We attributed this lack of reactivity, in part, to the need for the terminal amine arm to dissociate in these compounds to open a coordination site for the incoming lactide. 

New studies with analogous In complexes suggest that the central tertiary amine substituent in these complexes may also be important (see below).
