Reaction of 2,2-dimethyl-1,3-dioxin-4-ones with Imines, Carbodiimides, and Isocyanates

Sato, Masayuki,Ogasawara, Hiromichi,Kato, Tetsuzo

, p. 2602 - 2608 (2007/10/02)

The ring transformation of 2,2-dimethyl-1,3-dioxin-4-ones (1) to nitrogen heterocycles was studied.Heating of 1 whith imines such as Schiff bases gave rise to cycloadducts of imines to acylketenes (2), i.e., 3,4-dihydro-1,3-oxazin-4-one derivatives
