Synthesis and structure characterization of 14 N-  substituted phenyl- N'-[6-(2-substituted benzothiazol)yl]  urea compounds

Abstract

Seven N-substituted phenyl-N'-(6-benzothiazoly)-and seven N- substituted phenyl-N'-[6-(2-methyl-benzothiazol)yl] ureas were synthesized in 70.0% ～ 91.0% yields by a series of reaction of benzothiazole and 2-methyl-benzothiazole with substituted phenylamines, respectively, in search of new compounds with plant growth regulation activity. The structures of fourteen compounds were characterizated by elemental analysis、 IR and 1^H NMR. Preliminary cytokinin-activity of the compounds were determined.

Key words: PHENYL GROUP, UREA, ISOCYANIC ESTERS, BENZOTHIAZOLE P, STRUCTURE CHARACTERISTICS, PLANT GROWTH REGULATORS, SYNTHESIS METHODS
