-
N-Substituted N′-[6-methyl-2-oxido-1,3,2-dioxaphosphinino(5,4,-b)pyridine-2-yl]ureas have been accomplished by condensation of equimolar quantities of chlorides of various carbamidophosphoric acids (3) with 3-hydroxyl-6-methyl-2-pyridinemethanol (lutidine diol) (4) in the presence of triethylamine in dry toluene-tetrahydrofuran (1:1) mixture at 45-50°C. Their structures were established by elemental analyses, IR, 1H NMR, 13C NMR, and 31P NMR spectral data. Their antifungal and antibacterial activity is also evaluated. Most of these compounds exhibited moderate antimicrobial activity in the assays.

-
N-(substituted)-N'-(2,3-dihydro-5-benzoyl-2-oxido-1H-1,3,2-benzodiazaphosphol-2-yl) ureas were synthesized by reacting 3,4-diaminobenzophenone (4) with different chlorides of carbamidophosphoric acids (3) in the presence of triethylamine at 40-45 degrees C. Their 1H-, 13C- and 31P-NMR spectral data are discussed. The title compounds were screened for antifungal and antibacterial activity against the fungi Aspergillus niger and Fusarium solani and bacteria Escherichia coli and Staphylococcus aureus. These compounds showed higher antibacterial activity when compared with antifungal activity.
