General procedure for preparing mono- (3a-g) and disubstituted 1,4-naphthoquinones (4a-d, 4f-g) from 2,3-dichloro-1,4-naphthoquinone (1)
These findings could be useful in the development of MNQand other related 1,4-naphthoquinones
as potent anti-metastatic agents for future clinical use.
Figure 1 shows chemical structure of 2-[(4-hydroxyphenyl)amino]-1,4- naphthoquinone (Q7; 265.07 g/mol); it was synthesized by amination of 1,4-naphthoquinone with 4-hydroxyphenylamine, under aerobic conditions, using Ce[Cl.sub.3]*7[H.sub.2]O as the Lewis acid catalyst as previously reported .
