In the present study, 2-(4-bromophenyl carbamoyl)phenyl acetate was synthesized by the ammonolysis of 2-(chloro carbonyl)phenyl acetate. Its structure was confirmed by IR and 1H NMR. Its antifungal activity against Sclerotinia sclerotiorum and Botrytis cinerea has been determined in the laboratory. The results showed that it had good antifungal activity against the two different pathogenic fungi of plants. Its median effective concentrations (EC50) reached 8.6 mg L-1 and 1.8 mg L-1, respectively.
Using salicylic acid as a lead compound, a series of its analogues (compounds 1-16) were designed and synthesized. Their activity of anti-pathogenic fungi of plants has been evaluated in the laboratory. The results showed that these compounds had certain antifungal activity against Sclerotinia sclerotiorum and Bipolaris maydis (Nisikado et Miyake) Shoem. Among them, the inhibition of growth for 2-(3-fluorophenylcarbamoyl)phenyl acetate (1) and 2-(3-chlorophenylcarbamoyl)phenyl acetate (2) reached 91.1 %, 92.8 % and 90.1 %, 90.1 % at a concentration of 100 mg L-1, respectively.

A new class of salicylanilides is described. These compounds show strong activity against hepatitis viruses.
Synthesis and Antifungal Activity of Aspirin Derivatives
Using aspirin as a lead compound, a series of its derivatives (compounds 1-7) were designed and synthesized. Their activity of anti-pathogenic fungi of plants has been evaluated in the laboratory. The results showed that these compounds had good antifungal activity against Sclerotinia sclerotiorum, Helminthosprium maydis, Botrytis cinerea and Rhizoctonia solani. Among them, the inhibition of growth for compounds 1 and 2 against Helminthosprium maydis reached 92.5 and 91.6 % at a concentration of 100 mg L-1, respectively, which was superior to carbendazim.
