Aminocarbonyl naphthol derivatives and cyano naphthol derivatives and methods for their preparation

摘要

The below-mentioned formula the amino carbonyl naphthol derivative and its production person who are displayed with (1)[In formula, as for Y₁ and Y₂, amino carbonyl group and carboxyl group, formula (2),It is the basis which is selected from the group which consists of, Y at least as for one side of₁ and Y₂ is the amino carbonyl group]. In addition, the new cyano naphthol derivative and its salts which with the below-mentioned formula (7) are displayed[In formula, as for Y₇ and Y₈ in independence, cyano basis, formula (2), formula (3), formula (4), carboxyl group and amino carbonyl group;It is the basis which is selected from the group which consists of, Y at least one side of₇ and Y₈ is the cyano basis].
