With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.34946-82-2,Copper(II) trifluoromethanesulfonate,as a common compound, the synthetic route is as follows.

General procedure: Representative procedure for 17: A Schlenk tube was charged with 2 (400mg, 2.03mmol), dry THF (10mL), anhydrous cobalt(II) chloride and a stirring bar. In a separate Schlenk tube, a solution of lithium diisopropylamide (LDA) was prepared in THF (25mL) from diisopropylamine (700muL, 5.0 mmol) and n-butyl lithium (3.15mL of a 1.6M solution in hexane, 5.0 mmol). The LDA-solution was added under protection from air to the solution of 2 and CoCl2. After the mixture has been stirred overnight, all volatile materials were removed on a vacuum line. The Schlenk vessel was transferred into the glove-box and the dark colored solid residue was dissolved in a small volume of dry dichloromethane. Layering the solution with dry n-hexane afforded brown single crystals of the product.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.34946-82-2,Copper(II) trifluoromethanesulfonate,as a common compound, the synthetic route is as follows.

Tert-leucine phosphinoazomethinylate potassium salt (100 mg, 0.23 mmol, 1 eq.) and copper bis-triflate Cu(OTf)2 (114 mg, 0.23 mmol, 1 eq.) are placed in a round-bottom flask. Anhydrous THF is then added (9 mL, 40 mL per mmol). The reaction mixture is agitated at room temperature for 1 hour. The solvent is evaporated and the product is dried under reduced pressure. A green powder is obtained (210 mg, 98%).
