Enantiopure eaters are obtained in good yield from (-)-2,2-dimethyl-3-
formylcyclopropane-1-carboxylic acid (biocartol) in three steps: (1) d
ithiane protection of the aldehyde function; (2) esterification of the
carboxylic acid function; (3) dethioketalization. The X-ray structure
s of biocartol and of its acetal 'dimer' are reported.
