Abstract
A process for obtaining 2,8-dioxabicyclo [3,5,0] -octa-3,7-dione 7 its derivatives of the general formula; ** (see formula) ** Wherein x can be a metal or an organic base, characterized by a michael addition of ethyl malonate to ethyl 4-, 4-diethoxy-trichonate, in basic medium, followed by hydrolysis of the resulting product; the dilactone formed below can be opened with bases to form the salts corresponding to 2-formylglutaric acid.
