Racemic 2-hydronaphtoin has been resolved by formation of diastereoisomers with (-)-menthoxyacetyl chloride and fractional crystallization of menthoxyacetates. Enantiomers of 2,3,11-12-tetra (2-naphthyl)-18-crown-6 were obtained by condensation between ( + ) or (-)-2-hydronaphtoin and diethylene glycol ditosylate in the presence of potassium hydride as base and template.
