A new convenient synthesis of N-acyl-2-(dimethoxyphosphoryl)glycinates

Easily accessible N-acyl-2-triphenylphosphonioglycinate tetrafluoroborates react smoothly with trimethylphosphite in the presence of methyltriphenylphosphonium iodide to give N-acyl-2-(dimethoxyphosphoryl)glycinates in good or very good yields. The dimeth

4-Phosphoranylidene-5(4H)-oxazolones - A Novel Synthesis and Properties

4-Phosphoranylidene-5(4H)-oxazolones (2), a hardly known class of phosphorus ylides, were readily prepared from 4-unsubstituted-5-(4H)-oxazolones (1) by treatment with Ph3P-Br2, Bu3P-Br2, Ph3P-CCl4, or Ph3P-CBr4 adducts in the presence of triethylamine in CH2Cl2 at room temperature in a novel, efficient one-pot procedure. The spectroscopic properties of the ylides are reported and discussed.
