実験手順

Using a procedure analogous to that described for the preparation of 89D, 93D was reacted with 3,4-dimethoxyphenylboronic acid and glyoxylic acid monohydrate to give 93E. 1H NMR (400 MHz, CD3OD) δ ppm 3.73 (s, 3H) 3.80 (s, 3H) 3.81 (s, 3H) 5.07 (s, 1H) 6.39 (t, J=1.98 Hz, 1H) 6.75 (s, 1H) 6.81 (s, 1H) 6.92 (d, J=8.35 Hz, 1H) 7.07 (dd, J=8.35, 1.76 Hz, 1H) 7.11 (d, J=1.76 Hz, 1H).
