Palladium-Catalyzed ortho-Benzoylation of Sulfonamides through C?H Activation: Expedient Synthesis of Cyclic N-Sulfonyl Ketimines

The ortho-carbonylation of sulfonylarenes by non-hazardous aryl aldehydes as a carbonyl precursor was reported. In this method, the sulfonamide group serves as a directing group for C?H activation in the presence of a Pd catalyst under ligand-free conditions. The scope of this strategy has been extended to the one-pot two-step synthesis of cyclic N-sulfonyl ketimines under mild reaction conditions. Our approach could be considered as an alternative by circumventing the use of highly reactive organolithium or Grignard reagents to access a wide range of biologically potent cyclic N-sulfonyl ketimines.

SULFONAMIDE DERIVATIVES

The present invention relates to microbicides for agricultural or horticultural use containing sulfonamide derivative of, for example, a formula (I):or a salt thereof,[wherein A1is (1) an aryl group which may be substituted or (2) a heterocyclic group which may be substituted, X1is (1) a chemical bond, (2) a methylene group which may be substituted, or (3) a vinylene group which may be substituted, B1is a five-membered heterocyclic group comprising nitrogen or sulfur atoms as the ring-constructing atoms except for carbon atoms and may be substituted or a condensed heterocyclic group which may be substituted, Z1is (1) a hydrocarbon group which may be substituted, (2) an acyl group which may be substituted, (3) formyl group, (4) an amino group which may be substituted, (5) a group represented by -N=CR1R2(wherein each of R1and R2is a hydrogen atom or a hydrocarbon group which may be substituted), (6) a cyclic amino group, (7) a group represented by -OR3(wherein R3is a hydrogen atom, a hydrocarbon group which may be substituted, an acyl group which may be substituted, formyl group or an alkylsulfonyl group which may be substituted) or (8) -S(O)nR4(wherein n stands for an integer from 0 to 2, R4stands for a hydrogen atom or a hydrocarbon group which may be substituted). The said compounds or the salts thereof are sulfonamide derivatives with microbicidal action, areuseful as excellent microbicides for agricultural or horticultural use, because they are safe, and they have little influence on human beings, farm animals, natural enemies, or the environment, and exert excellent control effects even on resistant microbes.
