Abstract
The novel chiral phosphoramide, 1,4-bis[(5S)-1,3-diaza-2-phospha-2-oxo-3-ph enylbicyclo(3.3.0)octan-2-yl]piperazine, was synthesised and successfully e mployed as a catalyst in the borane-mediated asymmetric reductions of proch iral cc-halo ketones, providing the corresponding a-halo alcohols in 90-95% enantiomeric purities.
