Abstract

A process for synthesizing geranylgeraniol includes such steps as selectively oxidizing (E)-methyl of geranyl acetate by SeO2-tert-butyl hydrogen peroxide in dichloromethane to obtain mixed oxide, reducting by sodium borohydride in emthanol to obtain 8-geranyl hydroxy acetate, reacting on phosphorus tribromide in anhydrous ether under existance of pyridine to obtain trans-8-geranyl bromoacetate, condensation reacting on geranyl sulfone in N,N-dimethyl methylamide under existance of tert-butanol potassium to obtain 9-sulfogeranyl geraniol, and reducting by lithium in methylamine.

Description

technical field

[0001] The invention relates to a method for synthesizing geranylgeraniol. Background technique

[0002] Geranyl geraniol (all-trans-Geranylgeraniol, 3, 7, 11, 15-tetramethylhexadeca-2E, 6E, 10E, 14-tetraenol) is a straight-chain diterpenoid, and its molecular structure is:

[0003]

[0004] Geranylgeraniol itself has a wide range of physiological activities, such as anti-virus, anti-virus and anti-tumor, etc., and has therapeutic effects on many diseases, such as ulcers, neurasthenia, skin aging, thrombosis, atherosclerosis and immune deficiency, etc. (U.S. Patent No. 20030092144).

[0005] Geranylgeraniol is a biosynthetic precursor for a variety of biochemically important products, such as terpenoids, carotene, steroids, cholesterol, and paclitaxel (Taxol  )Wait.

[0006] Geranylgeraniol is also an important organic synthesis intermediate of various drugs, such as coenzyme Q n (I), vitamin K (II and III) series compounds, ...
