HCID 71526901Dec-9-en-1-yl oct-7-enoate

Procedure

Following the aforementioned procedure, diene was prepared from oct-7-enoic acid and dec-9-en-1-ol. The resulting yellow oil was purified by silica gel chromatography (50:1 hexanes: diethyl ether) to afford the desired product as a colorless oil. IR (neat): 3077 (m), 2926 (s), 2855 (s), 1736 (s), 1641 (m), 1462 (m), 1417 (m), 1351 (m), 1255 (s), 1168 (s), 1113 (m), 1076 (m), 993 (s), 909 (s), 734 (m), 632 (m); 1H NMR (400 MHz, CDCl3): δ 5.86-5.75 (2H, m), 5.02-4.91 (4H, m), 4.05 (2H, t, J=6.8 Hz), 2.29 (2H, t, J=7.6 Hz), 2.08-2.01 (4H, m), 1.67-1.59 (4H, m), 1.42-1.27 (14H, m); 13C NMR (100 MHz, CDCl3): δ 174.0, 139.2, 138.9, 114.5, 114.3, 64.5, 34.4, 33.9, 33.7, 29.5, 29.3, 29.1, 29.0, 28.8, 28.7, 28.6, 26.0, 25.0; HRMS (ESI+) [M+H]+ calcd for C18H33O2: 281.2481. found: 281.2475.
