Reaction Steps

Using a procedure analogous to that used to prepare 6D, 30C (730 mg, 2.0 mmol) was reacted with 5,5′,5′-tetramethyl-[2,2′]bi[[1,3,2]dioxaborinanyl] to give 30D (420 mg, 64%) as a brown oil. 1H NMR (400 MHz, MeOD) δ ppm 2.29 (s, 3 H) 2.94 (t, J=7.07 Hz, 2 H) 4.26 (t, J=7.07 Hz, 2 H) 7.11 (d, J=7.33 Hz, 1 H) 7.24 (d, J=7.58 Hz, 1 H) 7.33 (t, J=7.96 Hz, 1 H) 7.36-7.52 (m, 2 H) 7.56 (d, J=7.83 Hz, 1 H) 7.77 (s, 1 H).
