Abstract

Des couples d'énantiomères diastéréoisomères de spirophosphoranes ont été préparés en faisant réagir le trichlorophosphane sur l'acide céto-2-glutarique. Par cristallisation sélective, un couple a été isolé dont la structure a été déterminée par diffraction des rayons X. Les sels de triéthylammonium de thiolo et sélénospirophosphoranes ont été obtenus en faisant réagir le soufre ou (et) le sélénium sur les spirophosphoranes préparés à partir des acides phénylpyruvique et céto-2-glutarique. Tous ces résultats ont été rationalisés par des calculs semi-empiriques.
