The synthesis of spiro[cyclopropane-1,3′-oxindole]-2-carboxylic acid, including novel 3-(2- and 3-pyridyl)-substituted analogues and the novel cyclopropa[c]quinoline-7b-carboxylic acid and their ester and amide derivatives is described. These syntheses in

A herbicide containing as the active ingredient an N-(henylsulfonyl)picolinamide derivative represented by general formula (I) wherein X reprcsents a halogeno, a C1-4 alkyl, a C1-4 haloalkyl, a C1-4 alkoxy, a C1-4 haloalkoxy, a (C1-4 alkoxy)carbonyl, a [di(C1-4 alkyl)amino]sulfonyl, an [N—(C1-4 alkyl)-N—(C1-4 alkoxy)amino]sulfonyl, a (C1-4 alkylamino)sulfonyl, a C1-4 alkylthio, a C1-4 alkylsulfinyl, a C1-4 alkylsulfonyl, or nitro; n is an integer of 0 to 5; Y represets a halogeno, a C1-4 alkyl, a C1-4 haloalkyl, a C1-4 alkoxy, C1-4 haloalkoxy, a C1-4 alkylthio, a C1-4 haloalkylthio, amino, a C1-4 alkylamino, a di(C1-4 alkyl)amino, a (C1-4 alkoxy) C1-4 alkyl, a (C1-4 alkylthio) C1-4 alkyl, or nitro; and m is an integer of 0 to 4. This active ingredient is synthesized by condensing a substituted picolinic acid with a substituted benzenesulfonamide under dehydration, or by reacting the phenyl ester of a substituted picolinic acid with a substituted benzenesulfonamide in the presence of a basic compound.
