Article abstract of DOI:10.1016/S0040-4039(01)93764-5

E- and Z- isomers of spirocyclic 5-arylmethylene-1,3-dioxane-4,6-dione, useful synthons for enantiomerically pure cyclopropane-1,1-dicarboxylates, have been synthesized from 1-menthone.Their diastereofacial selectivity is explained by a boat conformation in their dioxanedione ring.
