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

N-(Substitutedaryl/cyclohexyl)-N'-[5-bromo-5-nitro-2-oxido-1,3,2-dioxaphosphorinane-2-yl]ureas RR'P(O)NHC(O)NHR' (5) were synthesized by the reactions of 2-bromo-2-nitro-1,3-propanediol (4) with chlorides of aryl/cyclohexyl carbamidophosphoric acids (3) in the presence of triethylamine at room temperature. Their ir, 1H, 13C and 31P nmr spectral data are discussed.

Synthesis and antimicrobial activity of<i>N</i>-(substituted)-<i>N</i>-[1,2,4,8,10,11-hexachloro-6-oxido-12<i>H</i>-dibenzo(<i>d,g</i>)(1,3,2)-dioxaphosphocin-6-yl]ureas
Substituted dibenzo dioxaphosphocin-6-yl ureas were synthesized by reacting hexachlorophene (4) with different carbamidophosphoric acid dichlorides (3) in the presence of triethylamine in dry toluene at 45-50 oC. Their IR, 1H, 13C and 31P NMR spectral data is discussed. These compounds were found to possess good antimicrobial activity.
Synthesis and Antimicrobial Activity of 1‐[(Substituted Carbamoyl)Amino]‐1<i>H</i>,3<i>H</i>‐1λ<sup>5</sup>‐[1,3,2]oxazaphospholo[3,4‐a]benzimidazol‐1‐ones
1‐[(Substituted carbamoyl)amino]‐1H,3H‐1λ5‐[1,3,2]oxazaphospholo[3,4‐a]benzimidazol‐1‐ones were synthesized by reacting benzimidazole 2‐methanol (4) with different chlorides of carbamidophosphoric acids (3) in the presence of triethylamine at 40–45°C. Their 1H, 13C, and 31P NMR spectral data were discussed. The title compounds were tested for their activity against the fungi Aspergillus niger and Fusarium
