Abstract

The invention discloses a preparation method of compounds for preventing and controlling plant virus disease: glucoside-1,4-pentadiene-3-ketone compounds containing acetoxyl groups and bioactivity, namely the compounds shown in the general formula (b) and a preparation method thereof. According to the preparation method, the glucoside-1, 4-pentadiene-3-ketone compounds containing the acetoxyl groups are synthesized by taking acetone, 2 or 4-substituted hydroxybenzaldehyde, substituted arylamine and acetyl bromoglucose as raw materials, ethanol and dichloromethane as solvents, dichloromethane as a catalyst and tetrabutylammonium bromide as a phase transfer catalyst. The compounds (f6), (f8), (f10), (f26) and (f28) have relatively good inhibitory effects on tobacco mosaic virus, cucumber mosaic virus and the like. The formula is shown in the description.

Description

technical field [0001] The invention relates to the field of chemical technology, in particular to a compound containing acetoxyglucoside-1,4-pentadien-3-one, a synthesis method of the compound and a method for treating tobacco mosaic virus disease and cucumber mosaic virus. disease, southern rice black-streaked dwarf virus and rice stripe blight virus. Background technique [0002] Plant virus disease is the second largest disease after fungus. Because of its serious harm and difficult control, it is often called "plant cancer". At present, inhibitors such as Ningnanmycin, morpholinidine hydrochloride, ribavirin and amino oligosaccharides are widely used to prevent and control plant virus diseases, but these agents have problems such as poor control effect and high use cost. Therefore, there is an urgent need to create new high-efficiency, low-toxic anti-plant virus agents to meet the needs of agricultural production. [0003] Natural products have the characteristics of...
