Cyclization of aroylacetic acids 2-carboxyphenylamides into 2-[(Z)-2-aryl-2-hydroxy-1-ethenyl]-4H-3,1-benzoxazin-4-ones. Crystal and molecular structure of 2-[(Z)-2-hydroxy-2-phenyl-1-ethenyl]-4H-3,1-benzoxazin-4-one
摘要:
2-Carboxyphenylamides of aroylacetic acids undergo cyclization when treated with dehydrating agents to give 2-[(Z)-2-aryl-2-hydroxy-1-ethenyl]-4H-3,1-benzoxazin-4-ones. Crystal and molecular structure ofthe latter phenyl derivative was studied by X-ray crystal lography.

During thermolysis 6-aryl-2,2-dimethyl-1,3-dioxin-4-ones react with alpha-mono- and alpha,alpha-dioxoketene aminals to yield 3-acetyl-6-aryl-2-benzoylamino-4-pyridones or 6-aryl-2-methylene-4-pyrimidones, respectively. A scheme of the formation of pyrido[2,3-d]pyrimidines from dioxinones and 1-amino-1-benzoylamino-1-bytene-3-one has been suggested.
