Application
Borylation of Triflate with Pinacolborane
Typical procedure: To a degassed solution of L-tyrosine triflate derivative (500 mg, 1.17 mmol) and NMM (0.129 mL, 1.17 mmol) in dioxane (5 mL) is added PdCl2(dppf).CH2Cl2 (4.8 mg, 0.0059 mmol) and pinacolborane (0.255 mL, 1.76 mmol) at room temperature. The reaction mixture is then stirred for 24 h at 80 ℃. After cooling to room temperature, the mixture is concentrated and directly purified by silica gel column chromatography (heptane : ethyl acetate = 3 : 1) to give the borylation product as a colorless viscous oil (445 mg, 94% yield).
