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.
