摘要：

Reaction of 1-methoxynaphthalene with 1-formylnaphthalene in presence of n-BuLi/TMEDA, followed by deoxygenation and demethylation gave the bisnaphthol 6. Oxidation of 6 with KOBr yielded the spironaphthalenones 4a-b and 5a-b. The spironaphthalenones 3a-c on reaction with NH2OH.HCl gave naphth[2,1-c]isoxazole derivatives 9a-c. While similar reaction of 4a-b gave the pyrrolotropones 11a-b, spironaphthalenones 5a-b afforded the naphth[1,2-c]isoxazole derivatives 12a-b.
