反応手順
4,5-dimethoxy-2-methoxymethoxybenzaldehyde (F2) was prepared in a similar manner for the preparation of 5-methoxy-2-methoxymethoxybenzaldehyde (F1) by using 4,5-dimethoxy-2-hydroxybenzaldehyde (1.75 g, 14.9 mmol) instead of 2-hydroxy-5-methoxybenzaldehyde in 76% (2.56 g): 1H-NMR (500 MHz, CDCl3) δ3.55 (s, 3H), 3.89 (s, 3H), 3.95 (s, 3H), 5.26 (s, 2H), 6.77 (s, 1H), 7.32 (s, 1H) 10.35 (s, 1H).
