    Project supported by the National Natural Scinece Foundation of China (No. 21272129) and the National Key Technologies R&D Program (No. 2011BAE06B05).

In order to study the multi-bioactivity of sulfonylurea (SU) derivatives, twelve novel 2-methyl-6-chlorobenzenesul-fonylureas were designed and synthesized according to the commercialized SUs skeletons. Their structures were confirmed by 1H NMR, 13C NMR and HRMS. The title compounds showed good herbicidal activity against dicotyledonous weeds by pot-culture method. For example, the herbicidal activity of 5b, 5i and 5j against Brassica napus, Amaranthus retroflexus was as effective as chlorsulfuron and monosulfuron. The in vitro antifungal test indicated that some of the target compounds exhibited good antifungal activity at the dosage of 50 mg·L-1.

Key words: sulfonylurea, chlorsulfuron, herbicidal activity, antifungal activity
