    • At shorter reaction times (3 days), a decrease in yield (21%) is observed, although the ee was higher (89%). The use of ethyl benzoylacetate instead of benzyl benzoylacetate as starting material with 2 as catalyst provided lower yield (61%) and ee (44%). Comparable results were previously reported by Jørgensen and coworkers (ref. 10)

    • A mechanism involving a diamine catalyst (diphenylethylenediamine), instead of the previously supposed imidazolidine catalyst, has been proposed:

    • A) would play a major role as catalyst. In a related case, a 1,4-cis heterocyclic diastereoisomer was shown to be more reactive than the trans isomer in an N-acylation process. This can be rationalized taking into account that substituents in trans relationship shield the nitrogen inhibiting a nucleophilic attack. For the related example, see:
