چکیده انگلیسی
A novel series of α-aminophosphonates containing chitosan moiety was obtained in high yields from reactions of chitosan with aromatic aldehydes and triphenylphosphite in the presence of lithium perchlorate as a catalyst. The structures of the synthesized compounds were confirmed by IR and 1H NMR spectral data. Compounds (1–4) showed high antimicrobial activities against Escherichia coli (NCIM2065), Serratia marcescens, Enterobacter cloacae, Shigella dysenteriae, Salmonella enterica and Proteus vulgaris as Gram-negative bacteria, Bacillus subtilis (PC1219) and Staphylococcus aureus (ATCC25292) as Gram-positive bacteria and Candida albicans as a fungus, at low concentrations (2.5–10 mg/mL).
