実験手順
Using a procedure analogous to that used to prepare 6D, 26A (600 mg, 2.54 mmol) was reacted with 5,5′,5′-tetramethyl-[2,2′]bi[[1,3,2]dioxaborinanyl] to give 26B (455 mg, 82%) as a white solid. 1H NMR (400 MHz, CD3OD) δ ppm 1.24 (t, J=7.47 Hz, 3 H) 3.01 (t, J=6.81 Hz, 2 H) 3.35 (q, J=7.32 Hz, 2 H) 4.42 (t, J=6.59 Hz, 2 H) 7.29 (d, J=7.91 Hz, 2 H) 7.56 (d, J=7.91 Hz, 2 H) 7.86 (dd, J=9.01, 1.98 Hz, 1 H) 7.99 (d, J=8.79 Hz, 1 H) 8.11 (d, J=2.20 Hz, 1 H) 10.12 (s, 1 H).
