Abstract
Novel P-chirogenic organophosphorus compounds of general formula (I), a process for the synthesis of the compounds of formula (I), and intermediate products of general formulae (II), (III) and (IV), as shown below, are involved in the synthesis of compounds (I).Metal complexes including compounds (I) as ligands are also described. The novel compounds and complexes are useful in asymmetric catalysis by transition metal complexes or organocatalysis, especially for asymmetric hydrogenation or allylation. Compounds of general formula (I) may be useful as agrochemical and therapeutic substances, or as reagents or intermediates for fine chemistry.
