Source of material The (N-tert-buty\-N-( 1 -diethylphosphono-(2,2-dimethylpropyl)) nitroxyde SGI [ 1 ]is transformed into the corresponding O-2-propionyl derivative thanks to the A. T. R. A. method, using CuBr, Cu(o) and Af,/V,yV',7V",/V"-pentamethyldiethylenetriamine (PMDETA) [2], The resulting acid is then coupled with (45)-4-benzyl-2 -oxazolidinone according to Evans method [3] . Discussion There are a short interaction between H14B and 05 (x+l, y, z): 2.580 A giving a chain along the a
more » ... Between this chain and the neighbouring one by the 2i axis, two short interactions are found:-H8-02 (-a + l,y + 0.5,-z;2.487Â)and -H9B-02(-jc + 1, y + 0.5,-z; 2.557 À).
