58 % ee | With (cycloocta-1,5-diene)-[(S,S)-2,2'-bis(ferrocenyl-phenylphosphino)-1,1'-biphenyl] rhodium tetrafluoroborate; hydrogen In dichloromethane at 20℃; for 16 h; Autoclave | K.3. Asymmetric catalyzed hydrogenationTypical procedure A solution of [Rh(COD)L*]BF4 (0.005 mmol, 1 molpercent) and substrate (0.5 mmol) in dry solvent (7.5 mL) was introduced in a stainless steel autoclave. The autoclave was closed, purged with hydrogen and then pressurized with hydrogen. After 16h of stirring at room temperature, the pressure was released to atmospheric pressure and the solution was transferred to a round bottom flask. The solvent was removed on a rotary evaporator to give a residue which was purified by column chromatography on silica gel to afford the hydrogenated product. The enantiomeric excess was determined by HPLC on chiral column.Results of aymmetric catalyzed hydrogenations by rhodium complexes of ligands (1-48) or (1-49) are presented in table 9 and 10.

> 90 % ee | With flavin mononucleotide; alpha-D-glucopyranose; glucose dehydrogenase from Thermoplasma acidophilum; old yellow enzyme 1 from Saccharomyces pastorianus; nicotinamide adenine dinucleotide phosphate In aq. buffer at 20℃; for 24 h; Enzymatic reaction | General procedure: Ene-reductase activity assays were performed at ambient temperature under anaerobic conditions (Coy Laboratory, Grass Lake, MI). For preparing reaction stock solution, individual substrates (see below) were dissolved in 50mM Tris–HCl (pH 7.5), supplemented with 200μM NADP+, 100mM glucose, and glucose dehydrogenase (GDH) from Thermoplasma acidophilum (2 units for IVTT reactions, 5 units for purified enzyme reactions). Individual substrate concentrations were chosen to ensure vmax conditions or maximum solubility. At these substrate levels, reaction times were adjusted for 10–50percent substrate conversion. To assay OYE activity in IVTT experiments, 20μL of the reaction stock solution was mixed with 2–10μL IVTT reaction mixture and the total assay volume was adjusted to 30μl with 50mM Tris–HCl (pH 7.5). To assay purified OYE1 variants, the enzyme (final concentration: 250nM) was added to 500μl reaction stock solution. Reaction progress was monitored by removing 30-μl aliquots from the assay solution and quenching them by mixing thoroughly with 30μL of ethyl acetate containing 1mM cyclohexanone as internal standard. A sample of the organic phase was collected and analyzed by GC (protocols: see below). The enantio/diasteriomeric excess were calculated by integration of product and substrate peak areas. Relative rates of conversion for individual substrates were calculated by dividing the measured rate of conversion for OYE1 variant over the corresponding rate for wild type OYE1. |

72% | With t-butyl bromide In acetonitrile for 0.833333 h; Reflux | General procedure: To asolution of the PMB ether (1 mmol) in acetonitrile (10 mL), t-BuBr (1.1 equiv)was added and stirred at reflux. After completion of the reaction (monitored byTLC), it was concentrated under reduced pressure and the resulting crude wasdissolved in ethyl acetate (50 mL) and washed with saturated sodiumhydrogenocarbonate (25 mL). The aqueous layer was extracted with ethylacetate (2 5 mL) and the combine organic layer was washed with brinesolution, dried (MgSO4), concentrated under reduced pressure and the residuewas purified by column chromatography (silica gel, EtOAc, cyclohexane) toafford the corresponding alcohol. |
