Abstract: Abstract 169ChemInform Abstract The dioxazolylbutenone (III), prepared by the reaction of dimethylfuran (I) with nitrosocarbonylbenzene (II), reacts with a number of nucleophiles (IV) to form the Michael adducts, which are semi-protected 1,4-diones. The products (V) are converted to the diketones (VI) and to the trisubstituted furans (VII). Reactions of other furans are also investigated. (IR-, MS-, 1H-, 13C-NMR-data, X-ray analysis for (V) (R: p-tolyl)).
