We have recently described'the pure self-immolative chirality transfer between the stereochemically defined (S)-N-benzyl-3-(hydroxymethyl)-4-methyl-1, 4-dihydropyridine (1) and benzoylformic ester. The methyl mandelate (2) produced was found to be greater than 95% enantiomerically pure (corrected for the enantiomeric purity of 1) and possessed the S configuration. This
