ASYMMETRIC SYNTHESIS XXⅧ:ENANTIOSELECTIVE REDUCTION OF AROMATIC KETONES CATALYZED BY NEW CHIRAL CATALYST-(4R,8R,9S)-CAMPHANE[8,9-b]-1,3,2-OXATHIOBOROLIDINE
摘要:
(4R,8R,9S)-Camphane[8,9-b]-1,3,2-oxathioborolidine prepared from (1R,2S,3R)-3-mercapto-camphol with borane was used as catalyst in the enantioselective reduction of aromatic ketones:moderate enantioselectivities with e.e.7.44%-51.04% have been obtained for aromatic ketones with 20% mol catalyst,73.78% e.e for ω-bromo acetophenone with 100% mol catalyst.
