Embodiment 1

[0026] The synthesis of embodiment 1 compound Ia (R (n)=H):

[0027] Dissolve 1.5 mmol of benzoyl chloride in 5 mL of tetrahydrofuran to prepare a tetrahydrofuran solution (5 mL) of benzoyl chloride (1.5 mmol).

[0028] The intermediate 2-hydroxyethyl-1-adamantanecarboxylate (0.336g, 1.5mmol), tetrahydrofuran (10mL) and the acid-binding agent triethylamine (1.8mmol) were mixed, stirred and dissolved, and gradually dissolved in an ice bath. A solution of benzoyl chloride (1.5 mmol) in tetrahydrofuran (5 mL) was slowly added dropwise. After the dropwise addition, react at room temperature for 2 h, then filter to remove the hydrochloride of triethylamine generated by the reaction, and the filtrate is subjected to rotary evaporation to remove solvent tetrahydrofuran, and the obtained rotary evaporation residue is separated by column chromatography (eluent is a volume ratio of 1: The mixed solution of ethyl acetate and petroleum ether in 5) to obtain a light yellow oily liquid, wh...

Embodiment 2

[0031] The synthesis of embodiment 2 compound Ib (R (n)=o-fluorine):

[0032] The intermediate 2-hydroxyethyl-1-adamantanecarboxylate (0.336g, 1.5mmol), tetrahydrofuran (8.5mL) and the acid-binding agent triethylamine (2.25mmol) were mixed, stirred and dissolved, and placed in an ice bath A solution (4 mL) of o-fluorobenzoyl chloride (1.5 mmol) in tetrahydrofuran was slowly added dropwise. After the dropwise addition, react at room temperature for 3h, then filter to remove the hydrochloride of triethylamine generated by the reaction, and the filtrate is subjected to rotary evaporation to remove solvent tetrahydrofuran, and the obtained rotary evaporation residue is separated by column chromatography (eluent is a volume ratio of 1: 3 (mixture of ethyl acetate and petroleum ether) to obtain a white waxy solid, that is, 1-adamantanecarboxylic acid-2-(2-fluorobenzoyloxy)ethyl ester, and the calculated yield was 64.9%.

Embodiment 3

[0035] Synthesis of Example 3 Compound Ic (R (n) = p-fluorine):

[0036] The intermediate 2-hydroxyethyl-1-adamantanecarboxylate (0.336g, 1.5mmol), tetrahydrofuran (8.5mL) and acid-binding agent triethylamine (2.0mmol) were mixed, stirred and dissolved, and placed in an ice bath A tetrahydrofuran solution (4 mL) of p-fluorobenzoyl chloride (1.5 mmol) was slowly added dropwise. After the dropwise addition, react at room temperature for 3h, then filter to remove the hydrochloride of triethylamine generated by the reaction, and the filtrate is subjected to rotary evaporation to remove solvent tetrahydrofuran, and the obtained rotary evaporation residue is separated by column chromatography (eluent is a volume ratio of 1: 3 mixed solution of ethyl acetate and petroleum ether) to obtain a white waxy solid, which is 2-(4-fluorobenzoyloxy)ethyl 1-adamantanecarboxylate, and the calculated yield is 55.7%.

Abstract

The invention discloses a 1-adamantanecarboxylic acid-2-(substituted benzoyloxy)ethyl ester compound and its synthesis method and application. The structural formula of the ester compound is shown in formula (I): in formula (I), H on the benzene ring is monosubstituted, disubstituted or unsubstituted by substituent R; n is an integer of 0~2, preferably 1~2 An integer of 2, n represents the number of substituent R on the benzene ring; when n=0, it means that the H on the benzene ring is not substituted; when n=1, it means that the H on the benzene ring is monosubstituted by a substituent R; n When =2, it means that the H on the benzene ring is disubstituted by the substituent R, and the substituent R in different substitution positions is the same or different; the substituent R is hydrogen, C1~C3 alkoxy, C1~C2 haloalkyl, halogen , preferably hydrogen, methoxy, ethoxy, trifluoromethyl, F, Cl or Br. The synthesis method of the 1-adamantanecarboxylic acid-2-(substituted benzoyloxy)ethyl ester compound of the present invention is simple, and it exhibits certain antitumor activity.

Description

technical field [0001] The invention relates to a 1-adamantanecarboxylic acid-2-(substituted benzoyloxy) ethyl ester compound and a synthesis method and application thereof. Background technique [0002] Adamantane has unique chemical and physical properties, and has been widely used in medicine (Chemical Reviews, 2013, 113(5): 3516-3604), pesticides (Chemical Reagents, 2016, 38(03): 224-230), photoelectric Materials (Tetrahedron, 2013, 69(48): 10357-10 360) and other fields. According to literature reports, adamantane derivatives have antitumor (Investigational New Drugs, 2009, 27 (6): 586-594, Applied Chemistry, 2018, 35 (4): 420-426), antiviral (Journal of Infectious Diseases, 1989,159(3):430-435, Chinese Journal of New Drugs, 2016,25(7):798-803), antidepressant (Journal of Lanzhou University, 1984,37(3):66-76, Biochemical Engineering, 2017, 3(01):70-72) and other biological activities have attracted extensive attention from drug developers. In addition, adamantane is ...
