An efficient reduction of nitro and bromine naphthalene derivatives
摘要:
Reduction of 1,5-dimethoxy-4-nitronaphthalene by hydrazine hydrate was optimized in the course of current study. Influence of metals, temperature and solvents upon the process was tested. Yield of the reaction was the highest in the presence of Zn powder in DMF. Moderate heating made the process slightly more efficient than that at room temperature, whereas high temperature led to a decreased yield. The current approach made it possible to exclude high pressure and diminish experimental costs.

The CYP1B1 enzyme is regarded as a potential target for cancer prevention and therapy. Based on the structure of α-naphthoflavone (ANF), diverse 2-arylbenzo[h]quinolone derivatives were designed, synthesized and evaluated as selectiveCYP1B1inhibitors. Compared with ANF, although few of the title compounds possessed comparable or slightly higher CYP1B1 inhibitory activity, these compounds displayed

Oxidative Dimerization of 4-Methoxynaphthylamines in the Presence of Semiconductors
Three types of 4-methoxynaphthylamines 4a-c were oxidized by treatment with metal oxides under molecular oxygen (02). 4-Methoxy-1-naphthylamine 4a and 4,6-dimethoxy-1-naphthylamine 4b, on treatment with TiO(2) under O(2), gave mainly 2-amino-1,4-naphthoquinone derivatives 5a and 5b, respectively whereas 4,8-dimethoxy-1-naphthylamine 4c afforded an unique carbazole 6c as the major product.
