実験手順

This compound was synthesized from 5-carboxypentyltriphenylphosphonium bromide (9.50 g, 20 mmol) and 2-trans-octenal (2.52 g, 20 mmol) in 10% HMPA-THF (100 mL) by Wittig reaction. Kugelrohr distillation yielded the product (1.91 g, 43%) as a pale yellow oil (bp 122-125° C./0.01 torr). IR: 3500-2500, 1730 cm-1 ; 1H-NMR: 0.95 (t, 3H), 1.40 (m, 10H), 2.30 (m, 6H), 6.00 (m, 4H), 11.30 (bs, 1H). Anal. Calcd. for C14H24O2 : C, 74.95, H, 10.78%; Found: C, 75.04, H, 10.80%.
