N-(2-氯吡啶-3-基)羰基-2′-取代芳基磺酰胺的合成及除草活性

Synthesis and herbicidal activity of N-(2-chloropyrid-3yl)carbonyl-2′-substituted arylsulfonamides

通过2-氯吡啶-3-甲酸与2-取代芳基磺酰胺的缩合反应合成了6个N-(2-氯吡啶-3-基)羰基-2′-取代芳基磺酰胺化合物,其结构经元素分析1、HNMRI、R确证。初步室内除草活性试验表明,化合物对根、茎的生长均有一定的抑制作用。

Six novel N-（2-chloropyrid-3-yl） carbonyl-2＇-substituted arylsulfonamides were synthesized through the condensation of 2-chloropyrid-3-yl formic acid with 2-substituted arylsulfonamides and characterized by elemental analyses, ^1HNMR and IR. The preliminary bioassays showed that some title compounds possessed good herbicidal activities.
