Abstract

Abstract Die Thermolyse von 2-Diazo-1, 3-diketonen 1 in Gegenwart der Dienophile RNCX bzw. RXCN führt zu 1, 4-Cycloaddition der primär gebildeten Acylketene an die CN-Doppel- bzw. Dreifachbindung, wobei 3, 5, 6-trisubstituierte 2H-1, 3-Oxazin-2, 4-dione 7 bzw. 2, 5, 6- trisubstituierte 4H-1, 3-Oxazin-4-one 8 gebildet werden.
