참여 물질

반응 단계

This compound was synthesized from p-propoxybenzaldehyde (3.26 g, 20 mmol, prepared from 1-bromopropane and 4-hydroxybenzaldehyde) and 5-carboxypentyltriphenylphosphonium bromide (9.50 g, 20 mmol) in THF (100 mL) by a Wittig reaction. Crystallization (petroleum ether) afforded the product (3.15 g, 60%) as white crystals (mp: 52-53° C.). IR: 3450-2500, 1730 cm-1 ; 1H-NMR: 1.00 (t, 3H), 1.48 (m, 2H), 1.67 (m, 2H), 1.82 (m, 2H), 2.35 (m, 4H), 3.92 (t, 2H), 5.72+6.05 (m, 1H), 6.35 (d, 1H), 7.05 (q, 4H), 10.40 (bs, 1H). Anal. Calcd. for C16H22O3 : C, 73.25, H, 8.45%. Found: C, 73.15, H, 8.45%. Z:E=30:70.
