Problems solved by technology

However, the current synthetic method still has two unsatisfactory places. First, the number and types of substituents are limited by aldehydes, and it is difficult to obtain compounds with multiple substituents and different substituents; second, most Coupling reactions generate cis-trans isomers at the same time, resulting in lower yields and difficulties in separation

Abstract

The invention discloses a method for synthesizing an anti-form stilbene compound and the application of the method in preparing anti-tumor medicines. According to the method, diketene and amine are in full reaction to compound N-substituent-3-oxobutanamide; then N-substituent-3-oxobutanamide is reacted with carbon disulfide and methyl iodide successively through one-pot reaction to compound alpha-oxo ketene dithioacetals; further, the alpha-oxo ketene dithioacetals is in condensation with replacement cinnamyl aldehyde to obtain alpha-((2E.4E)-5-aryl-2, 4-pentylene acyl) ketenedithioacetals; and finally, the anti-form stilbene compound is obtained through <5+1> aromatization reaction. Compared with the traditional method, according to the method, cis-isomer is avoided, the synthetic production and the utilization ratio of raw materials are high, the raw materials are chip and easy to obtain, the method and processing equipment are simple and feasible, and mass production is easy to realize. A stilbene derivative in this method has a notable restriction effect on multiple cancer cells, so that the stilbene derivative can be used for preparing the anti-tumor medicines, and the method has a high medical value and a wide market prospect.

Description

technical field [0001] The invention relates to a method for synthesizing trans-stilbene compounds and its application in the preparation of antitumor drugs. Background technique [0002] Stilbene compounds are a general term for a class of compounds with stilbene as the structural core, including stilbene, diphenylethyl, phenanthrene and their derivatives. Stilbene compounds are mainly distributed in the parenchyma of plants. The first natural stilbene compound was isolated from the Polygonaceae plant Rhubarb in 1822. [0003] In recent years, with the emergence of environmental problems and various pollutions, the incidence of cancer is far greater than before. This situation has prompted scientists to intensify research on anticancer drugs. Polyhydroxy stilbene compounds are currently the most widely and deeply studied stilbene compounds with various biological activities. Resveratrol is one of the representative compounds. Early studies have shown that resveratrol has...
