Abstract
Adducts of 2,5-dimethoxy-2,5-dihydrofuran with several dienes were obtained by the Diels-Alder reaction. The possibility of the participation of 2-methoxy-7-methyl-1,6-dioxaspiro-[4.4]-3-nonene as a dienophile in the diene synthesis was demonstrated for the first time. The structures of the adducts were confirmed by their IR spectra and catalytic hydrogenation.
