Abstract
The invention relates to a compound of the formula (I) or the formula (II) in which: W is an oxygen atom or a radical of the formula NH; X is hydrogen or an alkaline cation or a C1-C8 alkyl or a —(CH2)n3—C(R4)(R5)(R6) radical; X and R on the one hand and X and R1 on the other hand may independently form an optionally substituted cycle with 5, 6 or 7 links. The invention also relates to complexes of said compounds with at least one metal selected from the group comprising copper, palladium, ruthenium, iridium and rhodium, and to a method for the synthesis of these compounds. These compounds and complexes can be used in various asymmetrical catalysis methods.
