The present invention concerns phosphinate universal P-stereogenic chiral precursors of formula (I) for chiral ligands, preparation processes thereof and their use for the preparation of optically pure or enriched chiral ligands. Claimed are formula (I) compounds as stereoisomer, preferably enantiomer: (I) RO is a tertiary alkoxy group comprising at least 5 carbon atoms, R' is chosen in the group consisting of alkyl, alkenyl, alkynyl, heteroaryl and aryl groups, Examples for one of the claimed processes is: (II) An example for the use of such phosphinates to make other P- stereogenic ligands is (Ad means adamantyl): (III).
