Eight N (substituted pyrimidin 2 yl) N β (or γ )pyridinecarbonyl thioureas are synthesied and tested for biological activity.All of them are new compounds and their structures are comfirmed by IR, 1HNMR and elementary analysis.The preliminary biological test shows that some of the target compounds have excellent inhibitory activities against root and stalk of dicotyledon plant (such as rape) and a good regulating activity for plant growth of monocotyledon(such as corn).
Substructure Link Way” was used to devise and synthesize eight new compounds. Their structures were confirmed by IR, - 1H NMR and elemental analysis. The preliminary bioassay showed that some of these compounds have good plant growth regulating activities.
