| 摘要 |
This invention relates to cyclobutane derivatives having the formula WHEREIN R1 to R3, which may be the same or different, represent hydrogen atoms, halogen atoms, hydroxy, trifluoromethyl, benzyloxy, acyloxy groups, alkyl groups with 1 to 6 carbon atoms, alkoxy groups with 1 to 3 carbon atoms, phenyl, cyclohexyl, or 2 of the radicals R1 to R3 together represents a methylenedioxy group, R4 represents a hydrogen atom or an alkyl group with 1 or 2 carbon atoms, R5 represents a hydrogen atom or an alkyl group with 1 to 3 carbon atoms and R6 represents a phenyl group, which may be mono- or disubstituted by halogen atoms, trifluoromethyl, hydroxy, nitro, amino, benzyloxy, acyloxy groups, alkyl groups with 1 to 3 carbon atoms, alkoxy groups with 1 to 3 carbon atoms or alkylthio groups with 1 to 3 carbon atoms; or a pyridyl group, optionally substituted by a halogen atom, a hydroxy, nitro, amino, benzyloxy, acyloxy, carboxy group, a carbalkoxy group with 1 to 3 carbon atoms in the alkoxy, an alkyl group with 1 to 3 carbon atoms or an alkoxy group with 1 to 3 carbon atoms; TO SALTS THEREOF WITH PHYSIOLOGICALLY COMPATIBLE INORGANIC OR ORGANIC ACIDS OR BASES AS WELL AS TO PROCESSES FOR THEIR PREPARATION. |
