Zusammenfassung
Dem nachIngold undWeaver 1 aus Methantricarbonsäurediäthylesteranilid (1) durch Thermolyse darstellbaren Produkt kommt nicht die Struktur des 6-Anilino-3-phenyl-2,4-dioxo-3,4-dihydro-2H-1,3-oxazins (3), sondern die des 2,4-Dioxo-3,3-bis-(carboxyanilino)-1,2,3,4-tetrahydro-chinolins (6) zu.
Abstract
The thermolysis of diethyl methanetricarboxylate anilide has been re-examined and found to give mainly 2.4-dioxo-3.3-bis-(carboxanilino)-1.2.3.4-tetrahydro-quinoline (6) and not 6-anilino-3.4-dihydro-3-phenyl-2H-1.3-oxazin-2.4-dion (3) as proposed byIngold andWeaver 1.
