Yield:84 % ee
Reaction Conditions:
with 1,2-bis((2S,5S)-2,5-diphenylphospholan-1-yl)ethane;hydrogen;nickel(II) acetate tetrahydrate in 2,2,2-trifluoroethanol at 50; under 760.051 - 38002.6 Torr; for 24 h;Overall yield = 93 percent;
Steps:
2 Example 2:
General procedure: 1.8mg of nickel triflate and 1.25mg of (S,S)-Ph-BPE were added to a 10ml Schlenk reaction tube or autoclave, 2ml of trifluoroethanol was added and stirred at room temperature for 20 minutes, then 0.25mmol of different fats were added Family gamma- or delta-ketoacid substrates. Under the hydrogen pressure of 1-50 atm, the reaction temperature was 65°C for 24 hours. After the reaction, the product was then analyzed by gas chromatography, and the results were shown in Table 4:
