Synthesis and antimicrobial activity of some oxazaphosphinine oxides

2008 ARKIVOC  
A new family of phosphorus heterocycle, namely 2-substituted 3-[4-(2-oxo-3,4-dihydro-2λ 5benzo[e][1,3,2]oxazaphosphinin-3-yl)phenyl]-3,4-dihydrobenzo[e][1,3,2]oxazaphosphinin-2oxides (5a-j) has been synthesized by the condensation of 2-[[4-(2-hydroxy-benzylamino)phenylamino]methyl]phenol (1) with phosphorus oxychloride in presence of triethylamine in dry tetrahydrofuran, followed by the reaction with various phenols 3a-j. Alternatively, some of these compounds 5a-e were prepared by the
