DOCUMENT TYPE: Patent CA Section: 27 (Heterocyclic Compounds (One Hetero Atom)) Section cross-reference(s): 5, 10 The invention relates to sulfonamides I [R1 = H, alkyl, alkoxy, alkenyl, alkynyl; R2, R3, R4, R5 = hydrogen, halogen, alkyl, alkoxy or halomethyl; R2R3 = Ph, cyclopentyl, or cyclohexyl ring (whereby said ring can optionally be substituted with R2' and R3'); R2', R3' = H, halogen, alkyl, alkoxy or halomethyl; in the case (a), when R2, R3, R4 and R5 = H, X = Ph, substituted with a group -C(R6):NOR7; R6 = alkyl; R7 = alkyl, benzyl, alkenyl, haloalkyl, haloalkenyl, alkynyl, haloalkynyl; in case (b), when at least one of the groups R2, R3, R4 and R5 1 H, X = Ph, naphthyl or a five- or six-membered satd., partially unsatd., or arom. heterocycle, bonded by means of a C atom, comprising one to four heteroatoms from the group O, N or S, where X can be substituted as per the description]. The prepn. of I comprises reaction of 4-picolylamine II with sulfonic acid chlorides, XSO2Cl under basic conditions. Thus, N-methyl-N-[(4-pyridinyl)methyl]-4-[1-(ethoxyimino)ethyl]-benzenesulfona mide [I; R1 = Me, R2 = R3 = R4 = R5 = H, X = C6H4(CMe:NOEt)-4] was prepd. from 4-picolylamine via sulfonylation with 4-MeCOC6H4SO2Cl in Et2O contg. catalytic pyridine, imination with aq. EtONH2 in MeOH, and N-methylation with MeI in DMF contg. NaH. The invention further relates to methods for prodn. of said compds., agents comprising the same and use thereof for the control of fungal pests which are pathogenic to plants. The plant protection activity of I was detd. (70% phytoprotective effect vs. Alternaria solani and Sphaerotheca fuliginea). .
