Reaction Steps

Using a procedure analogous to that used to prepare 6D, 37D (670 mg, 1.7 mmol) was reacted with 5,5′,5′-tetramethyl-[2,2′]bi[[1,3,2]dioxaborinanyl] to give 37E (278 mg, 45%) as a brown oil. 1H NMR (400 MHz, CD3OD) δ ppm 1.16 (t, J=7.45 Hz, 6 H) 2.68 (q, J=7.41 Hz, 4 H) 3.03 (t, J=7.83 Hz, 2 H) 4.14 (t, J=7.82 Hz, 2 H) 7.13-7.29 (m, 2 H) 7.30-7.45 (m, 2 H) 7.59 (d, J=7.83 Hz, 1 H) 7.80 (s, 1 H) 9.42 (s, 1 H).
