Chiral diazaphospholidine ligands

The invention relates to chiral diazaphospholidines, to methods for their preparation, and to their use in catalysts for the asymmetric catalysis of organic reactions. The application relates to diazaphospholidine compounds of Formula 1 and Formula 2: where:A and B are independently selected from C(RR) and C(RR)C(RR);R, R, R, R, R, R, R, R, R, R, Rand Reach may not be present and each may be independently selected from H, halide -OH, -SOR(where Ris selected from a group as defined for R, R, Rand R), -SH, -NO, -NH, O, S, straight chain, branched chain, cyclic, saturated, non-saturated, substituted or non-substituted alkyl, hydroalkyl, carboalkyl, alkoxy, amino, alkenyl, aryl and -CHAr (where Ar is aryl or substituted aryl), preferably containing 1 to 6 carbons, or a silane containing 1 to 6 silicon atoms,wherein, where an R, R, R, R, R, R, R, R, R, R, Rand/or Rgroup is not present an unsaturated bond is formed;Rand Rare selected from H, -NH, -OH, halide or a substituted or non-substituted straight or branched chain alkyl or aryl; R, R, Rand Rare each independently selected from halide -OH, -SO, -SH, -NO, -NH, straight chain, branched chain, cyclic, saturated, non-saturated, substituted or non-substituted alkyl, carboalkyl, alkoxy, alkenyl, aryl and -CHAr (where Ar is aryl or substituted aryl), or a silane containing 1 to 6 silicon atoms;Rand Rare selected from H, straight, branched, cyclic, saturated, non-saturated, substituted or non-substituted alkyl, carboalkyl, alkoxy, alkenyl, aryl and -CHAr (where Ar is aryl or substituted aryl);R, R, R, R, Rare independently selected from halide -OH, -SO, -SH, -NO, -NH, straight chain, branched chain, cyclic, saturated, non-saturated, substituted or non-substituted alkyl, carboalkyl, alkoxy, amino, alkenyl, aryl and -CHAr (where Ar is aryl or substituted aryl), or a silane containing 1 to 6 silicon atoms; andX is a linking group containing 1 to 12 atoms;or a salt thereof.These compounds may be used as catalysts for asymmetric catalysts of organic reactions.
