    • An alternative mechanism involving zinc alkoxide-catalysed epimerisation of the α-stereocentres of syn-β-aryl-aldols 9i-l (or syn-β-aryl-1,3-oxazinane-2,4-diones 10i-l) was discounted because their acidities are similar to those of the α-stereocentres of syn-β-alkyl-aldols 9a-k that had been shown to rearrange with no loss of stereocontrol under these conditions.
