2-Amination of quinizarin via Michael addition of hydrazines or amines

Bifunctionalisation of 1,4-naphthoquinone by the Oxidative Addition of an Alkylamine and Iodine

Novel 2-iodo-3-(alkylamino) naphthalene-1,4-diones are formed in 33–70% yield by the reaction of alkylamine and 1, 4-naphthoquinone in the presence of iodine.

A General Procedure for the Efficient Synthesis of (Alkylamino)naphthoquinones

Alkylamino derivatives of naphthazarine, juglone, and naphthoquinone have been synthesized via their corresponding bromo-analogues, in high yields, especially in the case of naphthazarins.
