Synthesis of 2- and 4-Oxo-1H-1-azaanthracene-9,10-diones from 2-amino-1,4-naphthoquinone
摘要:
In spite of the poor nucleophilicity of its amino group, which is considered to have an ''amide like'' character, 2-amino-1,4-naphthoquinone reacts with beta-dielectrophiles to give 2-oxo- or 4-oxo-1H-1-azaanthracene-9,10-diones.
