Synthesis and antibacterial activity of 4-aryl-2-hydroxy-4-oxo-2-butenoic (aroylpyruvic) acids N-(4-guanidylsulfonylphenyl)amides
摘要:
Reaction of methyl aroylpyruvates with 4-aminobenzolsulfonylguanidine in acetic acid in the presence of anhydrous sodium acetate afforded N-(4-guanidylsulfonylphenyl)amides of 4-aryl-2-hydroxy-4-oxo-2-butenoic acids. Antibacterial activity of the synthesized compounds was studied.

out by reacting methyl esters of 3-R 1-4-R2-4-oxo-2-hydroxy-2 butenoic acid (I) with ethylenediamine (II) (method A). The reaction proceeds with yields of up to 94% in alcoholic medium in the presence of catalytic amounts of acetic acid. The simplest method for synthesizing methyl esters of I is the Claisen condensation [13]. We have found that yields as high as 76%, based on II, of final products are
