D. Basavaiah et al., A novel and effective chiral phosphoramide catalyst for the borane-mediated asymmetric reduction of prochiral alpha-halo ketones, TETRAHEDR-A, 12(4), 2001, pp. 685-689
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. (C) 2001 Elsevier Science Ltd. All rights reserved.
