AN EFFICIENT ROUTE TO AMINOANTHRAQUINONES AND DERIVATIVES VIA A DIELS-ALDER REACTION.

Article abstract of DOI:10.1016/S0040-4039(00)96555-9

Cycloadditions of (E)-1-N-carbobenzoxyamino-1,3-butadiene to naphtoquinones followed by aromatization of the adducts and deprotection of the amino group afford regioselective syntheses of -5 and -8 substituted aminoanthraquinones.
