Embodiment 1
[0039] Synthesis of method embodiment 1β-elemene monosubstituted methyl ether
[0040]
[0041] The β-elemene chloride mixture was dissolved in methanol, and the molar ratio of β-elemene chloride to methanol was 1:20. Then add the basic catalyst KOH, and the molar ratio of β-elemene chloride to KOH is 1:5. The reactants were reacted at 40°C for 1 hour under reflux to obtain the product β-elemene monosubstituted methyl ether. The NMR characterization results are as follows:
[0042] 1 H-NMR (CDCl 3 , TMS, 500MHz), δ(ppm): 0.94(s, 3H), 1.36-1.71(m, 6H), 1.64(s, 3H), 1.94-2.00(m, 2H), 3.24(s, 3H), 3.84(s, 2H), 4.52(s, 1H), 4.75(s, 1H), 4.81(s, 1H), 4.84(d, J=3.46, 1H), 4.90(s, 1H), 4.956(s, 1H), 5.74 (dd, J=11.20, 6.47, 1H).
Embodiment 2
[0043] Synthesis of method embodiment 2β-elemene monosubstituted ethyl ether
[0044]
[0045] The β-elemene chloride mixture is dissolved in ethanol, and the molar ratio of β-elemene chloride to ethanol is 1:15. Then add the basic catalyst Na 2 CO 3 , β-elemene chloride and Na 2 CO 3 The molar ratio is 1:6. The reactants were reacted at 40°C for 25 hours under reflux to obtain the product β-elemene monosubstituted ethyl ether, and the characterization results were as follows:
[0046] Infrared Characterization: IR V max : 3081, 1639, 1454, 1441, 1105, 905, 889.
[0047] NMR characterization: 1 H-NMR (CDCl 3 , TMS, 500MHz), δ (ppm): 0.94 (s, 3H), 1.15 (t, J=7.01, 3H), 1.36-1.44 (m, 3H), 1.49-1.62 (m, 3H), 1.94-2.08 (m, 2H), 3.40(q, J=6.97, 2H), 3.89(s, 2H), 4.52(s, 1H), 4.75(s, 1H), 4.82(s, 1H), 4.85(d, J = 6.37, 1H), 4.89 (s, 1H), 4.96 (s, 1H), 5.75 (dd, J = 17.36, 11.04, 1H).
