Biphenyldiphosphine compounds |
| abstract |
The present invention provides compounds of the formula n nwherein R is optionally substituted lower alkyl, cycloalkyl or aryl; R′ is alkyl or aryl; n is zero or an integer of 1 or 2; or an enantiomer thereof; or an enantiomeric mixture thereof. n The compounds of formula (I) are bridged C 2 -symmetric biphenyldiphosphine analogs and, thus, may be employed as ligands to generate chiral transition metal catalysts which may be applied in a variety of asymmetric reactions. The compounds of the present invention are easily accessible in high diastereomeric and optical purity according to the methods disclosed herein. |
