應用實例・文獻

Application

Copper (II) Triflate Catalyzed Regioselective Markovnikov Hydration of Alkynes

T1292

Typical Procedure (R¹ = 4-methoxybenznene, R² = H): Cu(OTf)₂ (72 mg, 20 mol%) and water (36 mg, 2 eq.) are added to a stirred solution of 1-ethynyl-4-methoxybenzene (132.2 mg, 1 mmol) in EtOAc (2 mL). The reaction mixture is stirred at 100 °C for 1 hr. After completion of the reaction, it is cooled to room temperature; water is added and extracted with EtOAc, dried over anhydrous Na₂SO₄ and concentrated. The residue is purified by column chromatography to give 4'-methoxyacetophenone (135 mg, 90%) as a white solid.

Application

Synthesis of Optically Active Oxazoline Derivatives via Asymmetric Desymmetrization of 1,3-Diols

Typical Procedure:
Amino diols (0.5 mmol), K₂CO₃ (207.3 mg, 1.5 mmol), and p-toluenesulfonyl chloride (190.7 mg, 1.0 mmol) are added to a solution of Cu(OTf)₂ (18.1 mg, 0.05 mmol) and (R,R)-2,2'-isopropylidenebis(4-phenyl-2-oxazoline) (16.7 mg, 0.05 mmol) in tert-butyl alcohol (2 mL). After stirring for 12 h at room temperature, water (10 mL) is added. The resulting mixture is extracted with AcOEt. After separation, the organic layer is washed with brine, and then dried over Na₂SO₄. Concentration and purification through flash column chromatography gives the product.
