## Abstract L'étude en RMN du ^1^H, ^13^C et ^31^P d'hétérocycles dioxaphospholaniques a permis d'identifier sans ambiguité la position des substituants sur le cycle et aussi d'accéder à un certain nombre d'informations relatives à la stéréochimie de la molécule.
## Abstract ^13^C NMR assignments previously given for A‐nuclei (C‐5, 6, 7, 8, 9, 10) of 5‐hydroxy‐isoflavones (Ie, IIe, IIIb) have been reconsidered on the basis of the proton‐coupled spectrum of 5‐hydroxy‐7, 4′‐dimethoxyisoflavone (Ie) (cf: __Bull. Soc. Chim. Belg., 76 n°6/473__, 1977). Furtherm
