Autor: Akihiro Noguchi, Ei-ichi Mano, Takachiyo Okuda, Masayuki Kuzuya
Publikováno v: Bulletin of the Chemical Society of Japan. 58:1149-1155
The reactions of 2-pyridones with benzyne were investigated in order to gain some insight into the structure–reactivity–chemoselectivity relationship involved in the tautomeric systems. All reactions examined have resulted in the formation of Die

DIELS–ALDER ADDUCTS FROM N-UNSUBSTITUTED TAUTOMERIC 2(1H)-PYRIDONE-2-HYDROXYPYRIDINES; 5,6-BENZO-2-AZABARRELENONES AND 5,6-BENZO-2-AZABARRELENES

Apparent anomalous behavior of polar substituents on the benzene ring in the regioselectivity of di-π-methane rearrangement of 5,6-benzo-2-azabicyclo[2.2.2]octadienones
Autor: Ei-ichi Mano, Takachiyo Okuda, Masayuki Kuzuya, Masanao Ishikawa, Harold Hart
Publikováno v: Tetrahedron Letters. 22:1613-1616
Polar substituent effects on the aromatic ring emerge in the regioselectivity of the di-π-methane rearrangement of the title compounds when they possess the structural feature of including the bridgehead carbon in a saturated ring; the importance of

A novel regiospecific intramolecular cycloaddition of an aromatic ring. Molecular orbital study of conjugated ketenes thermally generated from six-membered α-monocarbonyl azo-compounds
Autor: Fumio Miyake, Takachiyo Okuda, Masayuki Kuzuya
Publikováno v: J. Chem. Soc., Perkin Trans. 2. :1471-1477
When a methylene dichloride solution containing 4,4-diarylphthalazin-1(4H)-one(3) was warmed above –50 °C, nitrogen extrusion occurred to result in the formation of the quinonoid ketene (19). The quinonoid ketene thus generated underwent a facile
