In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 27258-33-9 as follows. 27258-33-9<\/a><\/p>\n

Example 4; Influence of the ligand Using the optimal conditions [Example 2] which leads to 85-87% ee with the ligand sd499, a ligand screening with a variety of N,O-ligands was carried out. The results are given in the following table. The best results were obtained with the ligands sd311b (91% ee) and commercially available (S)-2-piperidinyl-1,1,2-triphenylethanol at 5 mol% scale. As the latter one is known to be a somewhat slower ligand than the paracyclophane-based ligands and the derivatives of sd499, we repeated the experiment with 10 mol% of (S)-2-piperidinyl-1,1,2-triphenylethanol. This experiment gave 93% ee. The ligand is available in both enantiomeric forms.<\/p>\n
