A general and practical approach to benzimidazothiazepine and benzimidazothioether derivatives via an intramolecular nucleophilic addition/ring expansion rearrangement of aryl isothiocyanates promoted by the tert-amino effect has been developed. This reaction is catalyzed by low-cost camphorsulfonic acid and tolerates a broad substrate scope with complete atom economy. Structurally intriguing benzimidazothiazepine
The present invention provides a quinolone compound represented by General Formula (1)
or a salt thereof, wherein R
1
represents a hydrogen atom, etc.; R
2
represents a hydrogen atom, etc.; R
3
represents a phenyl group optionally being substituted with one or more substituents, etc.; R
4
represents a halogen atom; R
5
represents a hydrogen atom or halogen atom; R
6
represents a hydrogen atom; and R
7
represents a hydroxyl group, etc. The quinolone compound have a functional improvement effect, which suppresses progression of neurological dysfunction by inhibiting the chronic progression of Parkinson's disease or protecting dopamine neurons from the disease etiology, thereby prolonging the period before first administration begins.
