Embodiment 1

[0074] The preparation method of intermediate 14-beta-elemenol (compound 1)

[0075] Dissolve 100mmol of β-elemene in 20mL of dichloromethane and acetic acid mixed solution (V:V=2:1), slowly drop into sodium hypochlorite solution containing 180mmol of active chlorine in ice bath, and react in ice bath for 4h. The dichloromethane layer was separated, the aqueous layer was extracted three times with dichloromethane, the combined dichloromethane was concentrated to obtain a light yellow liquid crude product, without further purification, the liquid crude product was dissolved in 15 mL of anhydrous N,N-dimethylformaldehyde Add 200mmol of anhydrous sodium acetate under stirring to amide (DMF), and react at 100°C for 7h. The reaction solution was suction-filtered with diatomaceous earth, and the filtrate was added with 15 mL of saturated brine, and extracted three times with petroleum ether. The petroleum ether was concentrated to obtain a yellow liquid, which was separated by colu...

Embodiment 2

[0079] Preparation method of 4-(14-beta-elemeneoxy)-4-oxobutanoic acid (compound 2)

[0080] Dissolve 3mmol of 14-β-elemenol in 10mL of anhydrous dichloromethane, add 0.3mmol of DMAP, 0.3mmol of EDCI and 3.3mmol of succinic anhydride, and react at room temperature for 10h. The reaction solution was washed three times with 10% hydrochloric acid, and the dichloromethane layer was concentrated to obtain a pale yellow liquid. Column chromatography with petroleum ether: ethyl acetate = 8:1 (V:V) gave a colorless liquid product with a yield of 67%.

Embodiment 3

[0084] Preparation method of 5-(14-beta-elemenyloxy)-5-oxopentanoic acid (compound 3)

[0085] Dissolve 3mmol of 14-β-elemenol in 10mL of anhydrous dichloromethane, add 0.3mmol of DMAP, 0.3mmol of EDCI and 3.3mmol of glutaric anhydride, and react at room temperature for 10h. The reaction solution was washed three times with 10% hydrochloric acid, and the dichloromethane layer was concentrated to obtain a light yellow liquid. Column chromatography with petroleum ether: ethyl acetate = 8:1 (V:V) gave a colorless liquid product with a yield of 74%.

[0086] 1 H NMR (CDCl 3 ,300MHz)δ:1.00(s,3H),1.41-1.65(m,6H),1.74(s,3H),1.92-2.06(m,4H),2.44(t,J=7.3Hz,4H),4.49 (s,2H),4.71(s,2H),4.88(s,1H),4.90(d,J=4.7Hz,1H),4.95(s,1H),5.13(s,1H),5.75(dd, J 1 =17.8Hz,J 2 =10.4Hz,1H).

Description

technical field [0001] The invention relates to the fields of organic synthesis and medicinal chemistry, in particular to a class of β-elemene 14-position derivatives. The invention also discloses the preparation method of these β-elemene 14-position derivatives and their anti-atherogenic properties. applications in sclerosis. Background technique [0002] Cardiovascular and cerebrovascular diseases, including coronary artery disease and stroke, are the main fatal diseases in the world. In recent years, with the continuous improvement of people's living standards and changes in eating habits, the incidence rate has been increasing year by year. It is reported that 100 million people per year Sixty-seven million people died of cardiovascular disease. AS is the common pathophysiological basis of cardiovascular and cerebrovascular events and an important factor causing cardiovascular and cerebrovascular diseases and death. In recent years, studies have shown that the occurrenc...
