N-Phosphorylated lactams 2. Reversible phosphorylation of silyllactams

The phosphorylation of N-trimethylsilyllactams by phosphorus(III) acid chlorides results in corresponding N-phosphinolactams in high yields. The derivatives thus obtained have been used in the synthesis of N-phosphoryl- and N-thiophosphoryllactams. The reversibility of the reaction of phosphinolactams has been established. - Keywords: N-trimethylsilyllactams; reversible phosphorylation; N-phosphoryllactams, synthesis.

INVESTIGATIONS IN THE SYSTEM PHOSPHORUS TRICHLORIDE / 1,3-PROPANEDIOL

The reaction of phosphorus trichloride and 1,3-propanediol was reinvestigated.Besides 2-chloro-1,3,2-dioxaphosphorinane 1 3-chloropropyl-dichlorophosphite 2 was formed.Compound 1 and 2 were fluorinated to give the corresponding phosphorinane 3 and the phosphite 4, respectively.Proton NMR spectra were recorded at 360.08 MHz and simulated for 1 and 3.The 4-H and 6-H signals were treated not as first order but as AA'XX' systems.
