摘要

The Diels-Alder reaction 2-azadienes and 2-or 3-bromo-5-substituted naphthoquinones (R3= OH, OAc, OMe) led to a regiospecific synthesis of the corresponding 2- azaanthraquinones-3-ones. The results indicate that the bromine atom exerts a stronger regiochemical control in these cycloaddition than the 5-substituent.
