反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: According to Scheme 7: In analogy to the synthesis of (12a), but taking (R)-1-indanol instead, 1-[(S)-3-(4-fluoro-phenyl)-1-indan-1-yl-1,4,6,7-tetrahydro-pyrazolo[4,3-c]pyridin-5-yl]-ethanone (12b) was obtained. Rt=2.46 min (LC method 6). Detected mass: 376.17 [M+H+].

反应条件: temp:-30.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: Methyl 4-hydroxybenzenepropanoate (4.1 g, 22 mmol) was dissolved in tetrahydrofuran (50 mL) and the mixture was stirred at −30° C. (R)-1-Indanol (98% ee) (3.0 g, 22 mmol), 1,1′-(azodicarbonyl)dipiperidine (5.66 g, 22 mmol) and tributylphosphine (5.6 mL, 22 mmol) were added and the mixture was stirred at −30° C. for 23 hrs. Water was added and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine and dried over sodium sulfate. The mixture was concentrated under reduced pressure and the obtained oil was purified by silica gel chromatography (hexane to hexane/ethyl acetate=10:1) to give the title compound (4.4 g, yield 66%) as a yellow oil. were added the mixture was extracted with ethyl acetate The organic layer was washed with saturated brine dried over sodium sulfate The mixture was concentrated under reduced pressure the obtained oil was purified by silica gel chromatography (hexane to hexane/ethyl acetate=10:1)

反应条件: temp:60.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: In a 50-ml autoclave, 3.3 mg (0.005 mmol, S/C=1000) of RuCl(R,R)—O-HT-Tsdpen) was placed, and the autoclave was purged with nitrogen. Subsequently, 0.66 g (5.0 mmol) of 1-indanone and 4.4 ml of methanol were added thereto, then hydrogen gas was charged to 3.0 MPa. Subsequently, the mixture was stirred for 20 hours at 60° C. The reaction liquid was subjected to a GC analysis, and as a result, (R)-1-indanol was obtained at a conversion rate of 58.6% with an optical purity of 97.8% ee. the autoclave was purged with nitrogen The reaction liquid
