A clean and highly efficient catalytic aerobic reductive ring-cleavage of 3-methylanthra[l,2-c]isoxazole-6,ll-dione to 1-amino-2-acetylanthraquinone was performed using simple organic amines as organocatalysts and water as a green reaction medium.This method provides a new clean transformation of isoxazole-containing compounds to the corresponding ortho-amino ketones.The catalytic performance of various organic amines was carefully screened,and simple organic primary amines were found to be promising practi...
