1121-22-8, trans-Cyclohexane-1,2-diamine is a chiral-catalyst compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
In a 3 mL screw cap vial containing a magnetic stir bar 5- (benzyloxy) -pent-1-yl)(5- (benzyloxy) -pent-1-yne) (87.1 mg, 0.5 mmol),N-benzylhydroxylamine (67.7 mg, 0.55 mmol),RuCp (PPh3) 2Cl (18.1 mg, 0.025 mmol) and toluene (1.25 mL) were added and the mixture was stirred at a reaction temperature of 100 C for 24 hours.The progress of the reaction was monitored by TLC.After completion of the reaction, the mixture was passed through silica gel to remove the catalyst, and the silica was washed with ethyl acetate. The product solution was concentrated in vacuo and purified by silica gel chromatography.A yield of 22.5 mg (15%) was obtained. To a screw cap vial was added 5- (benzyloxy) -pent-1-yne (87.1 mg, 0.5 mmol)((¡À) -trans-diaminocyclohexane (33 mul, 0.275 mmol), N-hydroxybenzotriazole (74.3 mg, 0.55 mmol)RuCp (PPh3) 2Cl (18.1 mg, 0.025 mmol)And t-butanol (1.25 mL)And the reaction time was changed to 4 hours. The reaction was carried out in the same manner as in Example 1 to synthesize amide. 97 mg (78%) was obtained., 1121-22-8
As the paragraph descriping shows that 1121-22-8 is playing an increasingly important role.
