A series of N-nitrourea derivatives bearing various cycloalkyl were conveniently obtained via three steps including nitration, carbamic chlorination, and aminolysis reactions. The structures of all newly synthesized compounds were elucidated and confirmed by IR, 1H NMR, 13C NMR, and elemental analysis. The preliminary bioassay indicated that the target compounds exhibited moderate herbicidal activity against Amaranthus albus and Sorghum sudanense. However, some of the title compounds presented high plant growth regulating activity against rice.
