Ir is easily incorporated in the alloy as it has the same lattice structure as Pt. Moreover, Ir salts can be electroreduced by applying potentials ranging from 0.0 to −0.1 V vs. Ag/AgCl, similar to the ones needed for Pt salt reduction36,40. This illustrates the benefits of incor...
The intracellular NADPH insufficient supply is the main bottleneck to the synthesis of chiral alcohols by asymmetric reduction with whole-cell catalysis. Herein, we provide a novel strategy to strengthen intracellular NADPH supply through introducing an NADP + -dependent glyceraldehyde 3-phosphate dehydroge...

When the [Et 3NH]+[HFe 3(CO) 11]- as catalyst was used for asymmetric reduction of 1,1-diphenylacetone, high enantioselectivity up to 98% was achieved. Monitoring the reaction in situ by infrared spectroscopy, it could be conjectured that the carbonyl iron cluster Fe 3(CO) 12 kept ...
Aromatic ketoneAsymmetric Transfer Hydrogenation (ATH) has been an attractive way for the reduction of ketones to chiral alcohols. A great number of novel and valuable synthetic pathways have been achived by the combination usage of organometallic and coordination chemistry for the production of ...
