Embodiment 1

[0041] A synthetic route and specific synthetic method of D-bornyl ferulate are disclosed in this example, wherein the synthetic route is:

[0042]

[0043] Among them, 1a is dextroborneol, 2 is ferulic acid protected by phenolic hydroxyl group, R is a protecting group, and the ferulic acid protected by phenolic hydroxyl is condensed with dextroborneol under the catalysis of a condensation agent to obtain dextrorotary ferulic acid protected by phenolic hydroxyl group. Bornyl ester 3a, and then deprotected to obtain D-bornyl ferulic acid; the above-mentioned protecting group includes any one of the following: methyl, tert-butyl, triphenylmethyl, methoxymethyl, trimethyl silyl, tert-butyldimethylsilyl, benzyl and tetrahydropyranyl; the above-mentioned condensing agents include: dicyclohexylcarbodiimide, diisopropylcarbodiimide, 1-(3-di Methylaminopropyl)-3-ethylcarbodiimide, 4-dimethylaminopyridine, 1-hydroxybenzotriazole and 4-pyrrolidinylpyridine.

[0044] The synthetic me...

Embodiment 4

[0051] This embodiment discloses a synthetic route of L-bornyl ferulate, and the route is as follows:

[0052]

[0053] Among them, 1b is L-borneol, ferulic acid protected by phenolic hydroxyl group is condensed with L-borneol under the catalysis of a condensing agent to obtain L-bornyl ferulic acid ester 3b protected by phenolic hydroxyl group, and then deprotected to obtain L-bornyl ferulic acid ester.

[0054] The above-mentioned protecting groups include any one of the following: methyl, tert-butyl, triphenylmethyl, methoxymethyl, trimethylsilyl, tert-butyldimethylsilyl, benzyl and tetra Hydropyranyl; Ferulic acid protected by phenolic hydroxyl is condensed with L-borneol under the catalysis of a condensing agent to obtain L-bornyl ferulic acid protected by phenolic hydroxyl, and then deprotected to obtain L-bornyl ferulic acid.

Abstract

The invention discloses bornyl ferulate. The bornyl ferulate and a pharmaceutically acceptable prodrug are applied to pharmacy; the bornyl ferulate is applied to treatment of cerebrovascular diseases; the bornyl ferulate comprises two structures including dextral bornyl ferulate and levorotatory bornyl ferulate; the structure formula of the dextral bornyl ferulate is shown as the specification; the structure formula of the levorotatory bornyl ferulate is shown as the specification; the dextral bornyl ferulate is an enantiomer of the levorotatory bornyl ferulate. A synthesis process of the bornyl ferulate is simple and short; raw materials are easy to obtain and are toxin-free and harmless; the synthesis process is easy to control; no harmful products are generated; the synthesis process is an environment-friendly and economical process and can be widely applied to the production of medicines for treating the cerebrovascular diseases.

Description

technical field [0001] The invention belongs to the field of chemical medicine, and in particular relates to the synthesis and application of D-(L-)bornyl ferulic acid. Background technique [0002] Ferulic acid (4-hydroxy-3-methoxycinnamic acid), originally found in the seeds and leaves of the plant, is a phenolic acid extracted from plants such as Angelica, Chuanqiong, and Ferula, which has anti-inflammatory properties , anti-oxidation, anti-thrombotic and a variety of physiological activities, widely used in health care products, cosmetics, medicine, pesticides and food additives and other fields. [0003] After research, it was found that ferulic acid can inhibit the aggregation and release of platelets, can significantly inhibit the formation of experimental thrombus, regulate the body's immunity, clear and inhibit free radical reactions, and ferulic acid molecules can affect the structure and structure of biological macromolecules in the body through various ways. The...
