摘要:
Disclosed is a process for producing 6-aryloxyquinoline derivatives useful as insecticides or fungicides for agricultural and horticultural use. The process comprises a cyclization reaction step of reacting an anthranilic acid derivative represented by general formula (1) with a kenone in the presence of an acid to obtain a quinolone derivative and a condensation reaction step of reacting the quinolone derivative with a halogen compound or an acid anhydride to obtain a quinoline derivative.
摘要:
An objective of the present invention is to provide a process for producing 4-carbonyloxyquinoline derivatives useful as agricultural and horticultural pesticides and fungicides. The objective can be attained by a process for producing 4-carbonyloxyquinoline derivatives represented by general formula (1), the process including reacting a quinolone derivative with a halogenated compound or an acid anhydride in the presence of a phase transfer catalyst and a base.
摘要:
An objective of the present invention is to provide a crystal of 2-ethyl-3,7-dimethyl-6-(4-(trifluoromethoxy)phenoxy)quinoline-4-yl methyl carbonate having stable physicochemical properties. The objective is attained by a crystal of 2-ethyl-3,7-dimethyl-6-(4-(trifluoromethoxy)phenoxy)quinoline-4-yl methyl carbonate that exhibits a diffraction peak pattern shown in Fig. 1 as determined by powder X-ray diffractometry.
