Chiral intermediates useful for the preparation of hydroxyphosphine ligands |
| abstract |
The invention relates to a compound of formula (I), wherein R<1> is hydrogen or a hydroxyl protecting group; and R<2> and R<3> are same or different and are independently selected from halogen or -O-SO2-X; wherein X is -C1-C4 alkyl; C1-C4 alkyl substituted with one or more halogen; or substituted or unsubstituted phenyl wherein said phenyl substituent is selected from halogen, nitro and C1-C4 alkyl; provided that when R<3> is bromine, X is not p-toluyl; and a process for the preparation thereof. |
