The N‐acylglycines (I) react with the dichlorophosphite (II) in the presence of triethylamine to give the oxazaphospholine (IIIa) or a mixture of the isomeric oxazaphospholines (IIIb) and (IVb).

Triacyl Phosphorus Triamides. -The synthesis of novel phosphorus triamides, (II) and (IV), based on the reaction of lactams or carboxylic amides with PCl3 is accomplished. The amide substituents possess pseudo halide properties as shown for phosphite (IV) in reactions with proton-containing compounds (cf. (VI)) . -(MALENKO, D. M.; NESTEROVA, L. I.; LUK'YANENKO, S.
