A ruthenocenyl phosphino-oxazoline-ruthenium complex (RuPHOX-Ru) was applied successfully to the asymmetric hydrogenation of β-secondary amino ketones, directly affording the corresponding chiral γ-secondary amino alcohols in up to 99% yield and with 99% ee. Reaction with β-(benzylamino)-1-phenylpropan-1-one could be performed on a gram-scale with a relatively low catalyst loading (up to 2000 S/C). The resulting hydrogenated product could be used for the synthesis of synthetically useful compounds.

experimental part, p. 6678 - 6685 (2011/10/09)
4-Aryl-2,3-dihydro-4H-pyrimido[2,3-b]benzothiazoles (4-Ar-DHPBs) were synthesized and their catalytic activity and selectivity in kinetic resolution of a secondary alcohol as well as in the Steglich rearrangement and related reactions were evaluated. 4-Aryl-DHPBs showed low enantioselectivity in the acylative kinetic resolution of 1-phenylethanol. Conversely, they catalyzed the Steglich rearrangement with moderate to excellent enantioselectivity, demonstrating the possibility for remote stereocontrol by introduction of a substituent at the 4-position of DHPB.

Polymer-supported chiral sulfonamide catalyzed one-pot reduction of β-keto nitriles: A practical synthesis of (R)-fluoxetine and (R)-duloxetine
Wang, Guangyin,Liu, Xingshun,Zhao, Gang
, p. 1873 - 1879 (2007/10/03)
Enantioselective reduction of β-keto nitriles to optically active 1,3-amino alcohols has been carried out in one step using an excess of borane-dimethyl sulfide complex as a reductant and a polymer-supported chiral sulfonamide as a catalyst with moderate to high enantioselectivity. The facile and enantioselective method to prepare optically active 1,3-amino alcohols to be converted into 3-aryloxy-3-arylpropylamine-type antidepressant drugs (R)-fluoxetine, and (R)-duloxetine is also reported.

, p. 169 - 172 (2007/10/03)
(Matrix presented) Chiral Ru-TsDPEN [N-(p-toluenesulfonyl)-1,2- diphenylethylenediamine]-derived catalysts were first successfully immobilized onto amorphous silica gel and mesoporous silicas of MCM-41 and SBA-15 by an easily accessible approach. The catalyst immobilized on silica gel demonstrated remarkably high catalytic activities and excellent enantioselectivities (up to >99% ee) for the heterogeneous asymmetric transfer hydrogenation of various ketones. Particularly, the catalyst could be readily recovered and reused in multiple consecutive catalytic runs (up to 10 uses) with the completely maintained enantioselectivity.
