Ozonolysis of enol ethers. Part 10. Ozonization of enol ethers from 1,2- and 1,3-dicarbonyl compounds: Direct quantitative synthesis of phthalonic acid anhydride

The results of ozonolyses of enol ethers from 1.2- and 1.3-dicarbonyl compounds presented here strongly indicate that these reactions do not proceed via the established Criegee ozonolysis mechanism for nucleophilic C=C bonds. The quantitative one-step synthesis of phthalonic acid anhydride via ozonolysis of 2-(methoxymethyliden)-1H-inden-1.3(2H)-dione (28a) is described. Furthermore, a revision of the theory of alkene ozonolysis in the presence of tetracyanoethylene (TCNE) is proposed on the basis of a single-electron-transfer (SET) chemistry.

Heterocyclen aus α-Nitroolefinen. XII. 3-Acetyl-4,5-dihydro-5-(methyleneamino)furane und 3-Acylpyrrole aus α-Nitroolefinen und β-Diketonen

From α-nitroolefines 1 and β-diketones 2 3-acetyl-4,5-dihydro-5-(methyleneamino)furans 5 are prepared.Furans 5 react in acid medium to yield 1-unsubstituted 3-acylpyrroles 6, catalytic hydrogenation yields 1-substituted 3-acylpyroles 9.The (1)H-nmr and (13)C-nmr investigation prove the constitutions.
