A convenient and efficient synthesis of novel 1-ethoxycarbonylmethyl-3-ethyl-1,2,3,4-tetrahydro-4-oxo- 1,3,2-benzodiazaphosphorin-2-carboxamide 2-oxides

Some novel 1-ethoxycarbonylmethyl-3-ethyl-1,2,3,4-tetra- hydro-4-oxo-1,3,2-benzodiazaphosphorin-2-carboxamide 2-oxides containing α-amino acid ester or α -aminophosphonate groups have been designed incorporating the proximate carbonyl and phosphoryl groups into the benzoannulated phosphidiamide heterocycle and synthesized by a convenient one-pot procedure in good yields, in which the hydrochlorides of α-amino acid esters or hydrobromides of α -aminophosphonates reacted smoothly with bis(trichloromethyl) carbonate with the help of four molar equivalents of triethylamine to give the corresponding isocyanates that then formed the products by the addition with the phosphorus reagent containing a P-H bond.

A convenient synthesis of α-ureidomethylphosphonates with heterocycle moiety

Some novel heterocycle-substituted α-ureidoalkylphosphonates 3 have been synthesised through the reaction of α-isocyanatoalkylphosphonates with heterocyclic amines.

New and effective synthesis of unsymmetrical α-ureidoalkylphosphonates

An efficient synthesis of substituted α-ureidoalkylphosphonates 3 was reported. The method involves the conversion of α-aminoalkylphosphonates 1 to α-isocyanatoalkylphosphonates 2 by treating with triphosgene and followed by addition of substituted amine to 2. A new kind of cyclic α-ureidoalkylphosphonates 5 was also obtained by treating 2 with ?-aminobenzoic acid, followed by intramolecular cyclization of intermediate 4.
