Synthesis and antimicrobial activity of some new<i>N</i>-(substituted phenyl)-<i>N</i>′-[2,3-dihydro-2-oxido-3-(4′-fluorophenyl)-1<i>H</i>-(1,3,2)benzoxazaphosphorin 2-yl]ureas
Substituted benzoxazaphosphorin 2-yl ureas were synthesized by reacting 2-(4-fluoro-phenylamino)-methylphenol (4) with different carbamidophosphoric acid dichlorides (3) in the presence of triethylamine in dry toluene at 45-50 °C and characterized by spectral data. These compounds were found to possess good antimicrobial activity.
A b s t r a c t : Synthesis of A'-(Substituted)-jV-[5,5'bis(bromomethyl)-2-oxido-l,3,2-dioxaphosphormane-2yl] ureas has been accomplished by condensation of equimolar quantities of chlorides of various carbamidophosphoric acids 3 -with 2,2'-bis(bromomethyl)l,3-propanediol 4 in the presence of triethylamine in dry tetrahydrofuran at 30-40°C. Their structures were established by elemental analyses, IR
